What should come in place of question mark (?) in the following number series ?
400, 240, 144, 86.4, 51.84, 31.104, ?
Each number is 60 % of the previous number ,i.e. 0.6 is multiplied to each number.
400 $$\times 0.6$$ = 240
240 $$\times 0.6$$ = 144
144 $$\times 0.6$$ = 86.4
86.4 $$\times 0.6$$ = 51.84
51.84 $$\times 0.6$$ = 31.104
31.104 $$\times 0.6$$ = 18.6624
