यदि \(a_1=150\) और (a_{n+1}=a_n-\(2^n+n^2\)) है तो \(a_5\) क्या होगा?
If \(a_1=150\) and (a_{n+1}=a_n-\(2^n+n^2\)), what is \(a_5\)?
Explanation opens after your attempt
A. (100)
Concept
The subtracted values are (3,8,17,32), so \(a_5=90\). Exam tip: add all subtractions before subtracting.
Why this answer is correct
The correct answer is A. (100). The subtracted values are (3,8,17,32), so \(a_5=90\). Exam tip: add all subtractions before subtracting.
