यदि \(p_1=1\) और \(p_n=p_{n-1}+n^2-n\) है, तो \(p_5\) का मान क्या होगा?
If \(p_1=1\) and \(p_n=p_{n-1}+n^2-n\), what is the value of \(p_5\)?
Explanation opens after your attempt
A. इकतालीस(41)
Concept
\(p_5=1+2+6+12+20=41\). In exams, simplify \(n^2-n\) and then add.
Why this answer is correct
The correct answer is A. इकतालीस / (41). \(p_5=1+2+6+12+20=41\). In exams, simplify \(n^2-n\) and then add.
Exam Tip
\(p_5=1+2+6+12+20=41\) है। परीक्षा में \(n^2-n\) को सरल करके जोड़ें।
