Correct Answer

A. (4)

Step 1

\(a_{12}=71\) and \(a_{11}=67\), so the difference is (4). Exam tip: check the sign-changing part separately.

Step 2

Why this answer is correct

The correct answer is A. (4). \(a_{12}=71\) and \(a_{11}=67\), so the difference is (4). Exam tip: check the sign-changing part separately.

Step 3

Exam Tip

\(a_{12}=71\) और \(a_{11}=67\) इसलिए अंतर (4) है। चिह्न बदलने वाले भाग को अलग जाँचें।
