यदि \(a_1=12\) और \(a_{n+1}=\frac{a_n}{3}+2n\) है तो \(a_3\) क्या होगा?
If \(a_1=12\) and \(a_{n+1}=\frac{a_n}{3}+2n\), what is \(a_3\)?
Explanation opens after your attempt
C. (6)
Concept
\(a_2=\frac{12}{3}+2=6\) and \(a_3=\frac{6}{3}+4=6\). Exam tip: divide first and then add (2n).
Why this answer is correct
The correct answer is C. (6). \(a_2=\frac{12}{3}+2=6\) and \(a_3=\frac{6}{3}+4=6\). Exam tip: divide first and then add (2n).
Exam Tip
\(a_2=\frac{12}{3}+2=6\) और \(a_3=\frac{6}{3}+4=6\) है। पहले भाग करें फिर (2n) जोड़ें।
