In the following number series only one number is wrong. Find out the wrong number.

Question 114

6, 4, 5, 11, 39, 179, 1127

Solution

The pattern followed is :

6 $$\times 1 - 2$$ = 4

4 $$\times 2 - 3$$ = 5

5 $$\times 3 - 4$$ = 11

11 $$\times 4 - 5$$ = 39

39 $$\times 5 - 6$$ = 189 $$\neq 179$$

189 $$\times 6 - 7$$ = 1127
