Question : Directions: Select the number from among the given options that can replace the question mark (?) in the following series.
39, 53, ?, 108, 149, 199
Option 1: 81
Option 2: 72
Option 3: 79
Option 4: 76
Correct Answer: 76
Solution :
Given:
39, 53, ?, 108, 149, 199
The pattern is as follows –
39 + 14 = 53
53 + (14 + 9) = 53 + 23 = 76
76 + (23 + 9) = 76 + 32 = 108
108 + (32 + 9) = 108 + 41 = 149
149 + (41 + 9) = 149 + 50 = 199
So, 76 is the missing number of the series. Hence, the fourth option is correct.
