यदि \(a_1=100\) और \(a_{n+1}=a_n-n!\) है तो \(a_5\) क्या होगा?
If \(a_1=100\) and \(a_{n+1}=a_n-n!\), what is \(a_5\)?
Explanation opens after your attempt
C. (67)
Concept
The subtracted values are (1,2,6,24), so \(a_5=67\). Exam tip: write factorial subtractions in order.
Why this answer is correct
The correct answer is C. (67). The subtracted values are (1,2,6,24), so \(a_5=67\). Exam tip: write factorial subtractions in order.
Exam Tip
घटने वाले मान (1,2,6,24) हैं इसलिए \(a_5=67\) है। फैक्टोरियल घटावों को क्रम से लिखें।
