Correct Answer: 198


Solution : Given:
3, 6, 18, 21, 63, 66, ?

In the above-given series, add and multiply 3 alternatively to the previous term to get the next term –
3 + 3 = 6; 6 × 3 = 18; 18 + 3 = 21; 21 × 3 = 63; 63 + 3 = 66; 66 × 3 = 198

So, 198 is the missing term of the series. Hence, the fourth option is correct.
