Correct Answer: 93


Solution : Given:
2, 6, 9, 27, 30, 90, ?

In the above-given series, multiply and add 3 alternatively to the previous number to get the next number.
2 × 3 = 6; 6 + 3 = 9; 9 × 3 = 27; 27 + 3 = 30; 30 × 3 = 90; 90 + 3 = 93

So, 93 is the missing number of the series. Hence, the fourth option is correct.
