Question:
In the series 2, 6, 18, 54, ...... what will be the 8th term ?

Option A):
7434
Option B):
7443
Option C):
4374
Option D):
4370

Correct Answer is Option C):
4374

Explanation:
Clearly, 2 x 3 = 6, 6 x 3 = 18, 18 x 3 = 54,.....

So, the series is a G.P. in which a = 2, r = 3.

Therefore 8th term = ar8-1 = ar7 = 2 x 37 = (2 x 2187) = 4374.
