Reasons can be given for any of the numbers, but I suspect the required one is 100 as the other numbers are cubes (2³, 3³, 4³, 5³ & 6³).
125, 216, 343 and 512.
It is: 6*6*6 = 216
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' 1, 8. 27 . x . 125 . 216. 1^(3) , 2^(3) , 3^(3) , 4(3) , 5(3) , 6^(3) , .... n^(3) .
64, it's a list of cubes
