यदि \(z_1=1\), \(z_2=3\) और \(z_n=z_{n-1}z_{n-2}+n\) है, तो \(z_5\) का मान क्या होगा?
If \(z_1=1\), \(z_2=3\), and \(z_n=z_{n-1}z_{n-2}+n\), what is the value of \(z_5\)?
Explanation opens after your attempt
B. एक सौ सैंतीस(137)
Concept
\(z_3=6\), \(z_4=22\), and \(z_5=137\). In exams, multiply the previous two terms and then add (n).
Why this answer is correct
The correct answer is B. एक सौ सैंतीस / (137). \(z_3=6\), \(z_4=22\), and \(z_5=137\). In exams, multiply the previous two terms and then add (n).
Exam Tip
\(z_3=6\), \(z_4=22\) और \(z_5=137\) है। परीक्षा में पिछले दो पदों का गुणन करके (n) जोड़ें।
