Correct Answer

A. \(a_n=7n+5\)

Step 1

Concept

The difference is (7), and at (n=1) the value must be (12), so \(a_n=7n+5\). In exams, take the difference as the coefficient of (n).

Step 2

Why this answer is correct

The correct answer is A. \(a_n=7n+5\). The difference is (7), and at (n=1) the value must be (12), so \(a_n=7n+5\). In exams, take the difference as the coefficient of (n).

Step 3

Exam Tip

अंतर (7) है और (n=1) पर मान (12) चाहिए, इसलिए \(a_n=7n+5\) है। परीक्षा में अंतर को (n) का गुणांक मानें।
