Correct Answer

A. \(a_n=4n+27\)

Step 1

Concept

The first term is (31) and (d=4), so (a_n=31+(n-1)4=4n+27). Put (n=1) to check an option.

Step 2

Why this answer is correct

The correct answer is A. \(a_n=4n+27\). The first term is (31) and (d=4), so (a_n=31+(n-1)4=4n+27). Put (n=1) to check an option.

Step 3

Exam Tip

पहला पद (31) और (d=4) है इसलिए (a_n=31+(n-1)4=4n+27)। विकल्प की जांच के लिए (n=1) रखें।
