Question : Directions: Which of the following numbers will replace the question mark (?) in the given series?
134, 129, 122, ?, 102, 89
Option 1: 117
Option 2: 113
Option 3: 111
Option 4: 115
Correct Answer: 113
Solution :
Given:
134, 129, 122, ?, 102, 89
Subtract consecutive odd numbers starting from 5 from the previous term to obtain the next term.
134 – 5 = 129; 129 – 7 = 122; 122 – 9 = 113; 113 – 11 = 102; 102 – 13 = 89
So, 113 is the missing term in the given series. Hence, the second option is correct.
