Correct Answer: 196
Solution : Given: 109, 113, 122, 147, ?
Add the square of consecutive prime numbers in each number, to get the required number – 109 + (2)2 = 109 + 4 = 113, 113 + (3)2 = 113 + 9 = 122, 122 + (5)2 = 122 + 25 = 147, 147 + (7)2 = 147 + 49 = 196
So, 196 is the missing number in the series. Hence, the first option is correct.
