यदि \(c_1=3\) और (c_n=c_{n-1}+n(n-1)) है, तो कौन-सा कथन सही है?
If \(c_1=3\) and (c_n=c_{n-1}+n(n-1)), which statement is correct?
Explanation opens after your attempt
C. \(c_2=5\) और \(c_3=11\)\(c_2=5\) and \(c_3=11\)
Concept
\(c_2=3+2=5\) and \(c_3=5+6=11\). In exams, calculate (n(n-1)) newly for each term.
Why this answer is correct
The correct answer is C. \(c_2=5\) और \(c_3=11\) / \(c_2=5\) and \(c_3=11\). \(c_2=3+2=5\) and \(c_3=5+6=11\). In exams, calculate (n(n-1)) newly for each term.
Exam Tip
\(c_2=3+2=5\) और \(c_3=5+6=11\) है। परीक्षा में (n(n-1)) को हर पद पर नया निकालें।
