**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.
