64, it's a list of cubes
64 Each term number is cubed: 43 = 64
The given sequence consists of the cubes of the natural numbers: (1^3 = 1), (2^3 = 8), and (3^3 = 27). Following this pattern, the next number would be (4^3 = 64). Therefore, the missing number in the sequence is 64.
These numbers are cubes of the numbers 1,2,3,5 & 6, respectively. So 43 is missing, which is 64. It should go between 27 and 125.
