64 because it is basically cube each number in a row.

64

Your sequence seems to be a cubed sequence, but you are missing 64 between 27 and 125.13 = 123 = 833 = 2743 = 6453 = 12563 = 216So, next would be 73, which equals 343.

64 It is a series of cubes 13, 23, 33, 43, 53 etc

125 (each number is increased by the exponential 3n from the previous: +1, +3, +9, +27, +81)

These are perfect cubes (of 1, 2 and 3) so the next two are 64 and 125

64.The first number is 1 cubed, the second is 2 cubed, the third is 3 cubed, etc.

125 (each number is increased by the exponential 3n from the previous: +1, +3, +9, +27, +81)

64 should be between 27 and 125. (1 cubed equals 1. 2 cubed equals 8. 3 cubed equals 27. 4 cubed equals 64. Etc.)

125 (the sequence is successive numbers cubed)

The missing number in this sequence is 64, or 4 raised to the third power. You find the answer by noting that each number in the sequence is a counting number starting at 1 that is raised to the third power. For example, 2 raised to the third power (2 x 2 x 2) is 8.

13 ...23 ...33 ...43 ...53=125■
