Option 3: 148
Option 4: 150
Correct Answer: 144
Solution :
Given:
115, 130, 122, 137, 129, ?
Add 15 and subtract 8 alternately from the previous term to obtain the missing term.
115 + 15 = 130; 130 – 8 = 122; 122 + 15 = 137; 137 – 8 = 129; 129 + 15 = 144
So, 144 is the missing term in the given series. Hence, the first option is correct.
