यदि \(a_n=8n+q\) और \(a_{6n}-a_{2n}=384\) है, तो (n) का मान क्या है?
If \(a_n=8n+q\) and \(a_{6n}-a_{2n}=384\), what is the value of (n)?
Explanation opens after your attempt
C. (12)
Concept
(a_{6n}-a_{2n}=(48n+q)-(16n+q)=32n). From (32n=384), (n=12).
Why this answer is correct
The correct answer is C. (12). (a_{6n}-a_{2n}=(48n+q)-(16n+q)=32n). From (32n=384), (n=12).
Exam Tip
(a_{6n}-a_{2n}=(48n+q)-(16n+q)=32n)। (32n=384) से (n=12)।
