If (1,2,3) 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+1)

Step 1

Concept

The new terms are (a+1, a+d+2, a+2d+3), and both differences are (d+1). Adding increasing numbers respectively adds (1) to (d).

Step 2

Why this answer is correct

The correct answer is C. (d+1). The new terms are (a+1, a+d+2, a+2d+3), and both differences are (d+1). Adding increasing numbers respectively adds (1) to (d).

Step 3

Exam Tip

नए पद (a+1, a+d+2, a+2d+3) हैं और दोनों अंतर (d+1) हैं। क्रमशः बढ़ती हुई जोड़ से (d) में (1) जुड़ता है।

Explanation opens after your attempt
Correct Answer

C. (8)

Step 1

Concept

The two common differences are (3) and (5), so the sum sequence has (d=3+5=8). In termwise addition, common differences add.

Step 2

Why this answer is correct

The correct answer is C. (8). The two common differences are (3) and (5), so the sum sequence has (d=3+5=8). In termwise addition, common differences add.

Step 3

If each term of \(6, 11, 16, 21,\ldots\) is multiplied by (3), what will be the new common difference?

Explanation opens after your attempt
Correct Answer

C. (15)

Step 1

Concept

The original common difference is (5), so after multiplying by (3), the new (d=15). When all terms are multiplied by the same factor, (d) is multiplied by that factor too.

Step 2

Why this answer is correct

The correct answer is C. (15). The original common difference is (5), so after multiplying by (3), the new (d=15). When all terms are multiplied by the same factor, (d) is multiplied by that factor too.

Step 3

Exam Tip

मूल सार्व अंतर (5) है, इसलिए (3) से गुणा करने पर नया (d=15) होगा। सभी पदों को समान गुणक से गुणा करने पर (d) भी उसी गुणक से गुणा होता है।

If (5) is added to each term of \(10, 6, 2, -2,\ldots\), what will be the common difference of the new sequence?

Explanation opens after your attempt
Correct Answer

B. (-4)

Step 1

Concept

Adding the same (5) to all terms does not change (d), so (d=-4) remains. Equal addition or subtraction keeps the common difference unchanged.

Step 2

Why this answer is correct

The correct answer is B. (-4). Adding the same (5) to all terms does not change (d), so (d=-4) remains. Equal addition or subtraction keeps the common difference unchanged.

Step 3

Exam Tip

सभी पदों में समान (5) जोड़ने से (d) नहीं बदलता, इसलिए (d=-4) रहेगा। समान जोड़ या घटाव से सार्व अंतर अपरिवर्तित रहता है।

यदि (5x+2, 3x+10, x+18) अंकगणितीय श्रेणी में हैं, तो सार्व अंतर क्या है?

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।
