यदि \(a_1=5\) और \(a_{n+1}=a_n+\frac{3n}{2}\) है तो \(a_5\) क्या होगा?
If \(a_1=5\) and \(a_{n+1}=a_n+\frac{3n}{2}\), what is \(a_5\)?
Explanation opens after your attempt
C. (20)
Concept
The total addition is (\frac{3(1+2+3+4)}{2}=15), so \(a_5=20\). Exam tip: find the total fractional addition first.
Why this answer is correct
The correct answer is C. (20). The total addition is (\frac{3(1+2+3+4)}{2}=15), so \(a_5=20\). Exam tip: find the total fractional addition first.
Exam Tip
कुल जोड़ (\frac{3(1+2+3+4)}{2}=15) है इसलिए \(a_5=20\) है। भिन्न जोड़ में पहले कुल जोड़ निकालें।
