AI explanation

The pattern follows the formula of consecutive cubes plus 1, starting from 2. The sequence is 2 cubed plus 1 is 9, 3 cubed plus 1 is 28, 4 cubed plus 1 is 65, and it continues to 9 cubed plus 1 is 730. Based on this pattern, the first term should be 9 instead of 26, making 26 the wrong number.
