Identify the decimal number that will come next in the following series.
10, 9.9, 9.89, 9.889, 9.8889, .........
The pattern followed is that numbers of the form $$(\frac{1}{10})^n$$ are subtracted.
10 - $$0.1$$ = 9.9
9.9 - $$0.01$$ = 9.89
9.89 - $$0.001$$ = 9.889
9.889 - $$0.0001$$ = 9.8889
9.8889 - $$0.00001$$ =Â 9.88889
=> Ans - (D)
