यदि \(a_1=3\) और \(a_{n+1}=a_n+n^2\) है तो \(a_4\) क्या होगा?
If \(a_1=3\) and \(a_{n+1}=a_n+n^2\), what is \(a_4\)?
Explanation opens after your attempt
C. (17)
Concept
The terms are (3,4,8,17), so \(a_4=17\). Exam tip: add the new value of \(n^2\) at each step.
Why this answer is correct
The correct answer is C. (17). The terms are (3,4,8,17), so \(a_4=17\). Exam tip: add the new value of \(n^2\) at each step.
Exam Tip
पद (3,4,8,17) हैं इसलिए \(a_4=17\) है। हर चरण में \(n^2\) का नया मान जोड़ें।
