If \(a_n=2n^2-n+1\), which statement is correct?
Explanation opens after your attempt
A. \(a_2=7\) और \(a_3=16\)\(a_2=7\) and \(a_3=16\)
Concept
\(a_2=8-2+1=7\) and \(a_3=18-3+1=16\). In exams, use a separate value of (n) for each term.
Why this answer is correct
The correct answer is A. \(a_2=7\) और \(a_3=16\) / \(a_2=7\) and \(a_3=16\). \(a_2=8-2+1=7\) and \(a_3=18-3+1=16\). In exams, use a separate value of (n) for each term.
Exam Tip
\(a_2=8-2+1=7\) और \(a_3=18-3+1=16\) है। परीक्षा में प्रत्येक पद के लिए (n) का अलग मान रखें।
