Question : Directions: In the following question, select the missing number of the given series.
108, 129, 104, ?, 100, 137, 96
Option 1: 138
Option 2: 135
Option 3: 133
Option 4: 140
Correct Answer: 133
Solution :
Given:
108, 129, 104, ?, 100, 137, 96
Add and subtract alternatively starting with 21 in each number with a difference of 4, to get the required missing number –
108 + 21 = 129; 129 – 25 = 104; 104 + 29 = 133; 133 – 33 = 100; 100 + 37 = 137; 137 – 41 = 96
So, 133 is the required missing number of the series. Hence, the third option is correct.
