यदि \(a_1=3\) और \(a_{n+1}=a_n+n!\) है तो \(a_5\) क्या होगा?
If \(a_1=3\) and \(a_{n+1}=a_n+n!\), what is \(a_5\)?
Explanation opens after your attempt
B. (36)
Concept
The added values (1!,2!,3!,4!) are (1,2,6,24), so \(a_5=36\). Exam tip: add factorial values in order.
Why this answer is correct
The correct answer is B. (36). The added values (1!,2!,3!,4!) are (1,2,6,24), so \(a_5=36\). Exam tip: add factorial values in order.
Exam Tip
जुड़ने वाले मान (1!,2!,3!,4!) अर्थात (1,2,6,24) हैं इसलिए \(a_5=36\) है। फैक्टोरियल मान क्रम से जोड़ें।
