यदि \(N_1=8\) और (N_n=2N_{n-1}-n(n-1)) है, तो \(N_4\) का मान क्या होगा?
If \(N_1=8\) and (N_n=2N_{n-1}-n(n-1)), what is the value of \(N_4\)?
Explanation opens after your attempt
C. बत्तीस(32)
Concept
\(N_2=14\), \(N_3=22\), and \(N_4=32\). In exams, (n(n-1)) must be subtracted.
Why this answer is correct
The correct answer is C. बत्तीस / (32). \(N_2=14\), \(N_3=22\), and \(N_4=32\). In exams, (n(n-1)) must be subtracted.
Exam Tip
\(N_2=14\), \(N_3=22\) और \(N_4=32\) है। परीक्षा में (n(n-1)) को घटाना है।
