यदि \(a_n=\frac{n^2-1}{n+1}\) है तो \(a_{15}\) का मान क्या होगा?
If \(a_n=\frac{n^2-1}{n+1}\), what will be the value of \(a_{15}\)?
Explanation opens after your attempt
Correct Answer
C. (14)
Concept
\(\frac{n^2-1}{n+1}=n-1\). Therefore \(a_{15}=14\).
Why this answer is correct
The correct answer is C. (14). \(\frac{n^2-1}{n+1}=n-1\). Therefore \(a_{15}=14\).
Exam Tip
\(\frac{n^2-1}{n+1}=n-1\) होता है। इसलिए \(a_{15}=14\) है।
