What should come in place of the question mark (?) in the following number series?
Solution
Let the missing number be x
900-899 = (1)^2
899-891 = 8 = (2)^3
891-864 = 27 = (3)^3
864-800 = 64 = (4)^3
as we can see the pattern between differences of consecutive numbers is of type (n)^3
so x-800 = (5)^3,this implies that x= 675
