Question : Directions: Which number will replace the question mark (?) in the following series? 37, ?, 61, 78, 97, 120, 149
Option 1: 48
Option 2: 42
Option 3: 51
Option 4: 60
Correct Answer: 48
Solution : Given: 37, ?, 61, 78, 97, 120, 149
Add consecutive prime numbers to the previous number to get the next number of the series – 37 + 11 = 48; 48 + 13 = 61; 61 + 17 = 78; 78 + 19 = 97; 97 + 23 = 120; 120 + 29 = 149
So, 48 is the missing number of the series. Hence, the first option is correct.
