The cube numbers from 1 to 20 are 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1000. These correspond to the cubes of the integers from 1 to 10, specifically (1^3) to (10^3). The cube numbers within this range are thus 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1000.
1, 8, 27, 64, 125, 216, 343, 512, 729, 1000, 1331, 1728
It is: 1000 because they are all consecutive cubed numbers
64 125 216 343 512 729Bold numbers are the missing in the sequence
343.
216. That is because 125 is 5 cubed and 343 is 7 cubed, so 6 cubed is 216.
