अनुक्रम \(5,12,19,26,\ldots\) में पहले दो पदों का अंतर और तीसरे-चौथे पदों का अंतर क्या है?

In \(5,12,19,26,\ldots\), what are the difference of the first two terms and the difference of the third and fourth terms?

Explanation opens after your attempt
Correct Answer

A. (7) और (7)(7) and (7)

Step 1

Concept

The first difference is (12-5=7), and the second is (26-19=7). Equal differences confirm an arithmetic progression.

Step 2

Why this answer is correct

The correct answer is A. (7) और (7) / (7) and (7). The first difference is (12-5=7), and the second is (26-19=7). Equal differences confirm an arithmetic progression.

Step 3

Exam Tip

पहला अंतर (12-5=7) और दूसरा (26-19=7) है। समान अंतर समांतर श्रेढ़ी की पुष्टि करता है।

एक समांतर श्रेणी का सामान्य अंतर (d) है। \(a_1,a_3,a_5,\ldots\) से बने अनुक्रम का सामान्य अंतर क्या होगा?

An AP has common difference (d). What is the common difference of the sequence \(a_1,a_3,a_5,\ldots\)?

Explanation opens after your attempt
Correct Answer

B. (2d)

Step 1

Concept

The new sequence jumps two original terms each time, so the difference is (2d). In exams, multiply (d) by the term-number jump.

Step 2

Why this answer is correct

The correct answer is B. (2d). The new sequence jumps two original terms each time, so the difference is (2d). In exams, multiply (d) by the term-number jump.

Step 3

Exam Tip

नए अनुक्रम में दो-दो मूल पदों की छलांग है, इसलिए अंतर (2d) है। परीक्षा में पद-संख्या की छलांग को (d) से गुणा करें।

एक सीमित समांतर श्रेणी का सामान्य अंतर (-6) है। उसे उलटे क्रम में लिखने पर नया सामान्य अंतर क्या होगा?

A finite AP has common difference (-6). What will be the new common difference after writing it in reverse order?

Explanation opens after your attempt
Correct Answer

D. (6)

Step 1

Concept

Reversing changes each step to the opposite sign. In exams, reverse order changes (d) to (-d).

Step 2

Why this answer is correct

The correct answer is D. (6). Reversing changes each step to the opposite sign. In exams, reverse order changes (d) to (-d).

Step 3

Exam Tip

उलटने पर हर कदम का अंतर विपरीत चिन्ह वाला हो जाता है। परीक्षा में उलटा क्रम (d) को (-d) कर देता है।

An AP has common difference (4). What is the common difference of the new sequence \(a_2,a_5,a_8,\ldots\)?

Explanation opens after your attempt
Correct Answer

C. (12)

Step 1

Concept

The new sequence jumps three original terms each time, so its difference is (3d=12). In exams, count the gap between selected term numbers.

Step 2

Why this answer is correct

The correct answer is C. (12). The new sequence jumps three original terms each time, so its difference is (3d=12). In exams, count the gap between selected term numbers.

Step 3

Exam Tip

नए अनुक्रम में हर बार तीन पदों की छलांग है, इसलिए अंतर (3d=12) है। परीक्षा में चुने गए पदों के बीच की दूरी गिनें।

यदि \(a_n\) का सामान्य अंतर (-9) है और \(b_n=\frac{a_n}{3}+5\), तो \(b_n\) का सामान्य अंतर क्या होगा?

If \(a_n\) has common difference (-9) and \(b_n=\frac{a_n}{3}+5\), what is the common difference of \(b_n\)?

Explanation opens after your attempt
Correct Answer

C. (-3)

Step 1

Concept

Multiplying by \(\frac{1}{3}\) changes the difference from (-9) to (-3), and adding (5) does not change it. In exams, separate the effects of addition and multiplication.

Step 2

Why this answer is correct

The correct answer is C. (-3). Multiplying by \(\frac{1}{3}\) changes the difference from (-9) to (-3), and adding (5) does not change it. In exams, separate the effects of addition and multiplication.

Step 3

Exam Tip

\(\frac{1}{3}\) से गुणा करने पर अंतर (-9) से (-3) हो जाता है, और (5) जोड़ने से अंतर नहीं बदलता। परीक्षा में जोड़ और गुणन के प्रभाव अलग करें।

Correct Answer

D. (8)

Step 1

Concept

Multiplying terms by (2) multiplies the difference by (2), so it becomes (8). In exams, adding or subtracting a constant does not change the difference, but multiplication does.

Step 2

Why this answer is correct

The correct answer is D. (8). Multiplying terms by (2) multiplies the difference by (2), so it becomes (8). In exams, adding or subtracting a constant does not change the difference, but multiplication does.

Step 3

Exam Tip

पदों को (2) से गुणा करने पर अंतर भी (2) गुना हो जाता है, इसलिए (8)। परीक्षा में जोड़ना-घटाना अंतर नहीं बदलता, गुणा बदलता है।

If a new sequence is formed by termwise difference of \(1, 5, 9,\ldots\) and \(2, 8, 14,\ldots\), what will be its (d)?

Explanation opens after your attempt
Correct Answer

A. (-2)

Step 1

Concept

The first sequence has (d=4) and the second has (d=6), so the difference sequence has (d=4-6=-2). In termwise difference, take the difference of common differences.

Step 2

Why this answer is correct

The correct answer is A. (-2). The first sequence has (d=4) and the second has (d=6), so the difference sequence has (d=4-6=-2). In termwise difference, take the difference of common differences.

Step 3

Exam Tip

पहले अनुक्रम का (d=4) और दूसरे का (d=6) है, इसलिए अंतर अनुक्रम का (d=4-6=-2)। पद-दर-पद अंतर में सार्व अंतरों का अंतर लें।

अनुक्रम \(\frac{3}{8},\frac{5}{8},\frac{7}{8},\frac{9}{8},\ldots\) का सार्व अंतर क्या है?

What is the common difference of the sequence \(\frac{3}{8},\frac{5}{8},\frac{7}{8},\frac{9}{8},\ldots\)?

Explanation opens after your attempt
Correct Answer

B. \(\frac{1}{4}\)

Step 1

Concept

\(\frac{5}{8}-\frac{3}{8}=\frac{2}{8}=\frac{1}{4}\). When denominators are equal, subtract the numerators.

Step 2

Why this answer is correct

The correct answer is B. \(\frac{1}{4}\). \(\frac{5}{8}-\frac{3}{8}=\frac{2}{8}=\frac{1}{4}\). When denominators are equal, subtract the numerators.

Step 3

Exam Tip

If (2,4,6) are added respectively to (a,a+d,a+2d), what will be the new common difference?

Explanation opens after your attempt
Correct Answer

C. (d+2)

Step 1

Concept

The new terms are (a+2, a+d+4, a+2d+6), and both differences are (d+2). The difference (2) of the added numbers is also added to (d).

Step 2

Why this answer is correct

The correct answer is C. (d+2). The new terms are (a+2, a+d+4, a+2d+6), and both differences are (d+2). The difference (2) of the added numbers is also added to (d).

Step 3

Exam Tip

एक अंकगणितीय श्रेणी में पांचवें और दूसरे पद का अंतर (-18) है। (d) क्या होगा?

In an arithmetic progression, the difference between the fifth and second terms is (-18). What will (d) be?

Explanation opens after your attempt
Correct Answer

B. (-6)

Step 1

Concept

From the second to the fifth term there are (3) gaps, so (3d=-18) and (d=-6). In a decreasing progression, (d) remains negative.

Step 2

Why this answer is correct

The correct answer is B. (-6). From the second to the fifth term there are (3) gaps, so (3d=-18) and (d=-6). In a decreasing progression, (d) remains negative.

Step 3

Exam Tip

दूसरे से पांचवें पद तक (3) अंतर हैं, इसलिए (3d=-18) और (d=-6)। घटती श्रेणी में (d) ऋणात्मक रहता है।

Explanation opens after your attempt
Correct Answer

A. (d=-1) वाली अंकगणितीय श्रेणीArithmetic progression with (d=-1)

Step 1

Concept

The first has (d=4) and the second has (d=5), so the difference sequence has (d=4-5=-1). The termwise difference of two arithmetic progressions is also an arithmetic progression.

Step 2

Why this answer is correct

The correct answer is A. (d=-1) वाली अंकगणितीय श्रेणी / Arithmetic progression with (d=-1). The first has (d=4) and the second has (d=5), so the difference sequence has (d=4-5=-1). The termwise difference of two arithmetic progressions is also an arithmetic progression.

Step 3

If (5x+2, 3x+10, x+18) are in an arithmetic progression, what is the common difference?

Explanation opens after your attempt
Correct Answer

C. (4)

Step 1

Concept

Equating differences gives ((3x+10)-(5x+2)=(x+18)-(3x+10)), which is an identity, so (d=8-2x). Therefore it is an arithmetic progression for every (x), but (d) is not fixed.

Step 2

Why this answer is correct

The correct answer is C. (4). Equating differences gives ((3x+10)-(5x+2)=(x+18)-(3x+10)), which is an identity, so (d=8-2x). Therefore it is an arithmetic progression for every (x), but (d) is not fixed.

Step 3

Exam Tip

दोनों अंतर बराबर रखने पर ((3x+10)-(5x+2)=(x+18)-(3x+10)), जिससे पहचान समानता बनती है और (d=8-2x)। इसलिए यह हर (x) पर अंकगणितीय श्रेणी है, लेकिन (d) निश्चित नहीं है।
