यदि (a,a+d,a+2d) के तीनों पदों में क्रमशः (3,6,9) जोड़े जाएं तो नया सार्व अंतर क्या होगा?

If (3,6,9) 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+3)

Step 1

Concept

The new terms are (a+3,a+d+6,a+2d+9), and both differences are (d+3). The difference of the added numbers is added to (d).

Step 2

Why this answer is correct

The correct answer is C. (d+3). The new terms are (a+3,a+d+6,a+2d+9), and both differences are (d+3). The difference of the added numbers is added to (d).

Step 3

Exam Tip

What is the common difference of the sequence \(0.6,1.05,1.50,1.95,\ldots\)?

Explanation opens after your attempt
Correct Answer

C. (0.45)

Step 1

Concept

(1.05-0.60=0.45) and (1.50-1.05=0.45). Adding zeros makes decimal subtraction safer.

Step 2

Why this answer is correct

The correct answer is C. (0.45). (1.05-0.60=0.45) and (1.50-1.05=0.45). Adding zeros makes decimal subtraction safer.

Step 3

Exam Tip

If (7) is added to each term of \(24,20,16,12,\ldots\), 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 number to all terms does not change the common difference. The original (d=20-24=-4), so the new (d) remains (-4).

Step 2

Why this answer is correct

The correct answer is B. (-4). Adding the same number to all terms does not change the common difference. The original (d=20-24=-4), so the new (d) remains (-4).

Step 3

Exam Tip

सभी पदों में समान संख्या जोड़ने से सार्व अंतर नहीं बदलता। मूल (d=20-24=-4) है, इसलिए नया (d=-4) ही रहेगा।

B. (-4), ऋणात्मक(-4), negative

Step 1

Concept

Each next term is (4) less than the previous one, so (d=-4). A decreasing arithmetic progression has a negative common difference.

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
