यदि \(a_1=1\), \(a_2=5\) और \(a_n=2a_{n-1}-a_{n-2}+2\) है तो \(a_5\) क्या होगा?
If \(a_1=1\), \(a_2=5\), and \(a_n=2a_{n-1}-a_{n-2}+2\), what is \(a_5\)?
Explanation opens after your attempt
C. (29)
Concept
The terms are (1,5,11,19,29), so \(a_5=29\). Exam tip: subtract in the two-term rule and then add (2).
