AI explanation

The intended pattern follows the format where the first two digits increase by one (12, 23, 34, 45), the middle digit increases by one (4, 5, 6, 7), and the final digit increases by one (9, 9, 9, 9). By this logic, the third number should be 34669 instead of the listed 34659. Therefore, 34659 is the incorrect number in the sequence.
