Question

Select the number that can replace the question mark (?) in the following series.
12, 49, 197, 789, ?

A.

2341

B.

1845

C.

3157

D.

4029

Correct option is C

Given: 12, 49, 197, 789, ?
Logic: First number is multiplied by 4, then add 1 to get the next number.
Let's solve the given series: 
12×4+1=48+1=49 
49×4+1=196+1=197
197×4+1=788+1=789
789×4+1=3156+1=3157
So, the next number in the series is 3157.
Thus, the correct option is (C) 3157.
