यदि \(a_n=6n+q\) और \(a_{5n}-a_n=216\) है तो (n) का मान क्या है?
If \(a_n=6n+q\) and \(a_{5n}-a_n=216\), what is the value of (n)?
Explanation opens after your attempt
C. (9)
Concept
(a_{5n}-a_n=(30n+q)-(6n+q)=24n). From (24n=216), (n=9).
Why this answer is correct
The correct answer is C. (9). (a_{5n}-a_n=(30n+q)-(6n+q)=24n). From (24n=216), (n=9).
