Correct Answer

B. (11)

Step 1

Concept

For the first term (n=1), so \(a_1=9+2=11\). To find the first term from \(a_n\), put (n=1).

Step 2

Why this answer is correct

The correct answer is B. (11). For the first term (n=1), so \(a_1=9+2=11\). To find the first term from \(a_n\), put (n=1).

Step 3

Exam Tip

पहले पद के लिए (n=1), इसलिए \(a_1=9+2=11\)। \(a_n\) में पहला पद निकालने के लिए (n=1) रखें।
