यदि \(a_n=4n+r\) और \(a_{15}=83\) है तो \(a_{41}\) क्या होगा?
If \(a_n=4n+r\) and \(a_{15}=83\), what is \(a_{41}\)?
Explanation opens after your attempt
C. (187)
Concept
From (83=60+r), (r=23). Therefore \(a_{41}=4\times41+23=187\).
Why this answer is correct
The correct answer is C. (187). From (83=60+r), (r=23). Therefore \(a_{41}=4\times41+23=187\).
Exam Tip
(83=60+r) से (r=23)। इसलिए \(a_{41}=4\times41+23=187\)।
