Question 14

Select the number that can replace the question mark (?) in the following series.
39, 50, 63, 80, ?, 122, 147, 176

Solution

The series follows pattern as,
39 + 11 = 50
50 + (11 + 2 = 13) = 63
63 + (13 + 4 = 17) = 80
80 + (17 + 2 = 19) = 99

99 + (19 + 4  = 23) = 122
122 + (23 + 2 = 25) = 147
147 + (25 + 4 = 29) = 176
$$\therefore$$ The correct answer is option C.
