यदि किसी समान्तर श्रेणी में \(a_{16}=91\) और (d=6) है तो \(a_3\) क्या होगा?

If in an AP \(a_{16}=91\) and (d=6), what is \(a_3\)?

Explanation opens after your attempt
Correct Answer

D. (19)

Step 1

Concept

\(a_3=a_{16}-13d=91-78=13\). While moving backward, multiply the position gap by (d) and subtract.

Step 2

Why this answer is correct

The correct answer is D. (19). \(a_3=a_{16}-13d=91-78=13\). While moving backward, multiply the position gap by (d) and subtract.

Step 3

Exam Tip

\(a_3=a_{16}-13d=91-78=13\)। पीछे जाते समय स्थानों के अंतर को (d) से गुणा करके घटाएं।
