Correct Answer: 135


Solution : Given:
66, 87, 110, ?, 162, 191

Add consecutive odd numbers starting from 21 to the previous number to get the next number.
66 + 21 = 87; 87 + 23 = 110; 110 + 25 = 135​; 135 + 27 = 162; 162 + 29 = 191

So, 135 is the missing number. Hence, the fourth option is correct.
