The sequence (4x-3, 3x+5, x+21) is in an arithmetic progression. What is the common difference?

Explanation opens after your attempt
Correct Answer

A. (8)

Step 1

Concept

The differences are (-x+8) and (-2x+16). Equating them gives (x=8), so (d=0), not (8).

Step 2

Why this answer is correct

The correct answer is A. (8). The differences are (-x+8) and (-2x+16). Equating them gives (x=8), so (d=0), not (8).

Step 3

Exam Tip

अंतर (-x+8) और (-2x+16) हैं। बराबर करने पर (x=8), इसलिए (d=0) नहीं बल्कि (d=0) आता है।

यदि (9, y, 2y+6) समांतर श्रेणी में हैं, तो सामान्य अंतर क्या है?

If (9, y, 2y+6) are in an arithmetic progression, what is the common difference?

Explanation opens after your attempt
Correct Answer

B. (15)

Step 1

Concept

From (2y=9+(2y+6)), we get (0=15), so it never forms an arithmetic progression. None of the listed values can be its common difference.

Step 2

Why this answer is correct

The correct answer is B. (15). From (2y=9+(2y+6)), we get (0=15), so it never forms an arithmetic progression. None of the listed values can be its common difference.

Step 3

Exam Tip

(2y=9+(2y+6)) से (0=15) नहीं, इसलिए यह कभी समांतर श्रेणी नहीं बनती। सही विकल्पों में ऐसा कोई सामान्य अंतर नहीं है।

If a sequence is formed by termwise difference of \(6, 10, 14,\ldots\) and \(3, 8, 13,\ldots\), what type will it be?

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

Exam Tip

पहले (d=4) और दूसरे (d=5) हैं, इसलिए अंतर अनुक्रम का (d=4-5=-1)। दो अंकगणितीय श्रेणियों का पद-दर-पद अंतर भी अंकगणितीय श्रेणी होता 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।
