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

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

Correct Answer is Option B):
4374

Explanation:
Clearly, 2x3 = 6, 6x3 = 18, 18x3 = 54 So, the series is a G.P. in which a = 2 and r = 3. 8th term = ar(8-1) = ar(power7) = 2 x 3(power7) = (2 x 2187) = 4374.
