Option 3: 124
Option 4: 133
Correct Answer: 124
Solution :
Given:
24, 25, 33, 60, ?, 249
Add the cube of natural numbers starting from 1 to get the required missing number –
24 + 1
3
= 25; 25 + 2
3
= 33; 33 + 3
3
= 60; 60 + 4
3
= 124; 124 + 5
3
= 249
So, the required missing number in the series is 124. Hence, the third option is correct.
