यदि \(a_1=120\) और (a_{n+1}=a_n-\(n!+2^n\)) है तो \(a_5\) क्या होगा?
If \(a_1=120\) and (a_{n+1}=a_n-\(n!+2^n\)), what is \(a_5\)?
Explanation opens after your attempt
D. (57)
Concept
The subtracted values are (3,6,14,40), so \(a_5=57\). Exam tip: find the sum of all subtractions first.
Why this answer is correct
The correct answer is D. (57). The subtracted values are (3,6,14,40), so \(a_5=57\). Exam tip: find the sum of all subtractions first.
Exam Tip
घटने वाले मान (3,6,14,40) हैं इसलिए \(a_5=57\) है। पूरे घटावों का योग पहले निकालें।
