Explanation

The sequence consists of cubes: 1^3=1, 2^3=8, 3^3=27, 4^3=64, 5^3=125. 100 is not a perfect cube.

AI explanation

The sequence represents the cubes of consecutive natural numbers: 1 cubed is 1, 2 cubed is 8, 3 cubed is 27, 4 cubed is 64, and 6 cubed is 125. The term 100 is a perfect square, not a perfect cube. The correct term should be 5 cubed, which is 125; therefore, 100 is the wrong term.
