Select the number that can replace the question mark (?) in the following series.
1, 27, 125, 343, 729, ?

Solution

The given series is 1, 27, 125, 343, 729, ?

1 = 1$$^3$$

27 = 3$$^3$$

125 = 5$$^3$$

343 = 7$$^3$$

729 = 9$$^3$$

Similarly, the next number in the series = 11$$^3$$ = 1331

$$\therefore\ $$Required number = 1331
