Correct Answer: 88


Solution : Given:
75, 76, 78, 79, 81, 82, 84, 85, 87, ?

In the above-given series, add 1 and 2 alternately to the numbers of the given series.
75 + 1 = 76; 76 + 2 = 78; 78 + 1 = 79; 79 + 2 = 81; 81 + 1 = 82; 82 + 2 = 84; 84 + 1 = 85; 85 + 2 = 87; 87 + 1 = 88

So, the missing number is 88. Hence, the second option is correct.
