Correct Answer

C. (35)

Step 1

Concept

\(a_{10}-a_2=8d=40\), so (d=5) and (a_7=10+5(5)=35). Find the common difference first.

Step 2

Why this answer is correct

The correct answer is C. (35). \(a_{10}-a_2=8d=40\), so (d=5) and (a_7=10+5(5)=35). Find the common difference first.

Step 3

Exam Tip

\(a_{10}-a_2=8d=40\), इसलिए (d=5) और (a_7=10+5(5)=35)। पहले समान अंतर निकालें।
