यदि \(a_1=5\) और \(a_{n+1}=a_n+n!+n\) है तो \(a_5\) क्या होगा?
If \(a_1=5\) and \(a_{n+1}=a_n+n!+n\), what is \(a_5\)?
Explanation opens after your attempt
A. (48)
Concept
The added values are (2,4,9,28), so \(a_5=48\). Exam tip: add both the factorial and (n).
Why this answer is correct
The correct answer is A. (48). The added values are (2,4,9,28), so \(a_5=48\). Exam tip: add both the factorial and (n).
Exam Tip
जुड़ने वाले मान (2,4,9,28) हैं इसलिए \(a_5=48\) है। फैक्टोरियल और (n) दोनों जोड़ें।
