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
D. (19)
Concept
\(a_3=a_{16}-13d=91-78=13\). While moving backward, multiply the position gap by (d) and subtract.
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.
Exam Tip
\(a_3=a_{16}-13d=91-78=13\)। पीछे जाते समय स्थानों के अंतर को (d) से गुणा करके घटाएं।
