यदि \(v_1=3\) और \(v_n=v_{n-1}+n^3\) है, तो \(v_4\) का मान क्या होगा?
If \(v_1=3\) and \(v_n=v_{n-1}+n^3\), what is the value of \(v_4\)?
Explanation opens after your attempt
B. एक सौ दो(102)
Concept
\(v_4=3+8+27+64=102\). In exams, add the cube \(n^3\) correctly.
Why this answer is correct
The correct answer is B. एक सौ दो / (102). \(v_4=3+8+27+64=102\). In exams, add the cube \(n^3\) correctly.
Exam Tip
\(v_4=3+8+27+64=102\) है। परीक्षा में घन \(n^3\) को सही जोड़ें।
