Correct Answer: 116


Solution : Given:
74, 93, ?, 145, 176, 213

Add the consecutive prime numbers (starting from 19) to the previous number to get the next number in the series.
74 + 19 = 93; 93 + 116; 116 + 29 = 145; 145 + 31 = 176; 176 + 37 = 213

So, 116 is the missing number of the series. Hence, the second option is correct.
