यदि \(d_1=2\) और \(d_n=d_{n-1}+4n\) है, तो \(d_n>60\) पहली बार किस (n) पर होगा?
If \(d_1=2\) and \(d_n=d_{n-1}+4n\), for which (n) will \(d_n>60\) first occur?
Explanation opens after your attempt
D. छह(6)
Concept
\(d_5=58\) and \(d_6=82\), so the value first exceeds (60) at (n=6). In exams, choose the first term that becomes greater.
Why this answer is correct
The correct answer is D. छह / (6). \(d_5=58\) and \(d_6=82\), so the value first exceeds (60) at (n=6). In exams, choose the first term that becomes greater.
Exam Tip
\(d_5=58\) और \(d_6=82\), इसलिए पहली बार (n=6) पर मान (60) से अधिक होता है। परीक्षा में पहले से अधिक होने वाला पद चुनें।
