Question : Directions: Which number will replace the question mark (?) in the following series?
58, 59, 51, 78, 14, ?
Option 1: 97
Option 2: 139
Option 3: 83
Option 4: 163
Correct Answer: 139
Solution :
Given:
58, 59, 51, 78, 14, ?
The pattern is as follows –
58 + (1)
3
= 58 + 1 = 59
59 – (2)
3
= 59 – 8 = 51
51 + (3)
3
= 51 + 27 = 78
78 – (4)
3
= 78 – 64 = 14
14 + (5)
3
= 14 + 125 = 139
So, 139 is the missing number of the series. Hence, the second option is correct.
