Choose the correct alternative from the given responses that will complete the series:

Question 35

18, 54, 162, 486, 1458, ?

Solution

The logic here is

18 x 3 = 54

54 x 3 = 162

162 x 3 = 486

486 x 3 = 1458

It is a geometric progression with each successive term 3 times of the previous one.

Hence, the last term will be 1458 x 3 = 4374
