Correct Answer

A. \(a_n=26-4n\)

Step 1

Concept

The first term is (22) and (d=-4), so (a_n=22+(n-1)(-4)=26-4n). Keep (d) negative in a decreasing sequence.

Step 2

Why this answer is correct

The correct answer is A. \(a_n=26-4n\). The first term is (22) and (d=-4), so (a_n=22+(n-1)(-4)=26-4n). Keep (d) negative in a decreasing sequence.

Step 3

Exam Tip

पहला पद (22) और (d=-4) है इसलिए (a_n=22+(n-1)(-4)=26-4n)। घटते क्रम में (d) को ऋणात्मक रखें।
