In the following number series only one number is wrong. Find out the wrong number.
1, 8, 28, 99, 412, 2075, 12460
The pattern is :
1 $$\times 1 + (7 \times 1)$$ = 8
8 $$\times 2 + (6 \times 2)$$ = 28
28 $$\times 3 + (5 \times 3)$$ = 99
99 $$\times 4 + (4 \times 4)$$ = 412
412 $$\times 5 + (3 \times 5)$$ = 2075
2075 $$\times 6 + (2 \times 6)$$ = 12462 $$\neq 12460$$
