Correct Answer

A. (103)

Step 1

Concept

The cube additions are (1,8,27,64), so \(a_5=103\). Exam tip: add the new value of \(n^3\) at each step.

Step 2

Why this answer is correct

The correct answer is A. (103). The cube additions are (1,8,27,64), so \(a_5=103\). Exam tip: add the new value of \(n^3\) at each step.

Step 3

Exam Tip

घन जोड़ (1,8,27,64) हैं इसलिए \(a_5=103\) है। हर चरण में \(n^3\) का नया मान जोड़ें।
