Correct Answer

C. (24)

Step 1

Concept

\(a_9-a_2=7d=35\), so (d=5) and (a_5=9+3(5)=24). Find the common difference first.

Step 2

Why this answer is correct

The correct answer is C. (24). \(a_9-a_2=7d=35\), so (d=5) and (a_5=9+3(5)=24). Find the common difference first.

Step 3

Exam Tip

\(a_9-a_2=7d=35\), इसलिए (d=5) और (a_5=9+3(5)=24)। पहले समान अंतर निकालें।
