Correct Answer: 481


Solution : Given :
5, 16, 51, 158, ?

The next term can be obtained by multiplying the previous term by 3 and adding consecutive odd numbers to the resultant.
(5 × 3) + 1 = 15 + 1 = 16;
(16 × 3) + 3 = 48 + 3 = 51;
(51 × 3) + 5 = 153 + 5 = 158;
(158 × 3) + 7 = 474 + 7 = 481

So, the missing number is 481. Hence, the first option is correct.
