In the following number series only one number is wrong. Find out the wrong number.
12000, 2395, 472, 89.8, 12.96, -2.408, -5.4816
Each number is divided by 5 and then 5 is subtracted
12000 $$\div 5 - 5$$ = 2395
2395 $$\div 5 - 5$$ = 474 $$\neq 472$$
474 $$\div 5 - 5$$ = 89.8
89.8 $$\div 5 - 5$$ = 12.96
12.96 $$\div 5 - 5$$ = -2.408
-2.408 $$\div 5 - 5$$ = -5.4816
