The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.

If the last number is 1/3 (it should be), the next number is 5 and 1/3

The sequence represents the cube of integers starting at 1 and increasing by 1 at each step. 13 = 1 : 23 = 8 : 33 = 27 : 43 = 64 : then next two numbers are 53 = 125 : 63 = 216
