यदि \(a_n=n^3+n^2\) है तो \(a_8-a_6\) का सही मान क्या है?
If \(a_n=n^3+n^2\), what is the correct value of \(a_8-a_6\)?
Explanation opens after your attempt
C. (324)
Concept
\(a_8=512+64=576\) and \(a_6=216+36=252\). Therefore \(a_8-a_6=324\).
Why this answer is correct
The correct answer is C. (324). \(a_8=512+64=576\) and \(a_6=216+36=252\). Therefore \(a_8-a_6=324\).
Exam Tip
\(a_8=512+64=576\) और \(a_6=216+36=252\) है। इसलिए \(a_8-a_6=324\) है।
