**Directions:**

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

**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 = ar^{8-1} = ar^{7} = 2 x 3^{7} = (2 x 2187) = 4374.
