*Directions to Solve*

Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.

44.

24, 60, 120, 210, ?

Answer: Option

Explanation:

The pattern is + 36, + 60, + 90,.....i.e. + [6 x (6 + 0)], + [6 x (6 + 4)], + [6 x (6 + 9)],...

So, missing term = 210 + [6 x (6 + 15)] = 210 + 126 = 336.

Pattern is +36,+60,+90 .. i.e. + 6*6 , + 6*10 , + 6*15..

Therefore next difference will be + 6*21 as difference between 6, 10, 15, 21 is 4, 5 and 6 respectively.

Therefore 210+(6*21) = 336.

Therefore next difference will be + 6*21 as difference between 6, 10, 15, 21 is 4, 5 and 6 respectively.

Therefore 210+(6*21) = 336.

This pattern also works out as :-

3^3 - 3 = 24

4^3 - 4 = 60

5^3 - 5 = 120

6^3 - 6 = 210

Missing term = 7^3 - 7 = 336

3^3 - 3 = 24

4^3 - 4 = 60

5^3 - 5 = 120

6^3 - 6 = 210

Missing term = 7^3 - 7 = 336
