125, 216, 343 and 512.
216
It is: 6*6*6 = 216
216. It's the cube of 6.
Suppose 216 is 24% of X that means 100*216/X = 24 or X = 100*216/24 = 900
512
343.
In the list of cubes, the next number is 216.
27= 3364=43125=53so next number will be 63 = 216
5 x 5 x 5 = 125 6 x 6 x 6 = 216 7 x 7 x 7 = 343
64 because each number is cubed
64, 125 and 216
