A Correct answer
Explanation

The sequence follows the pattern n³ - 1: 0 = 1³ - 1, 7 = 2³ - 1, 26 = 3³ - 1, 63 = 4³ - 1, 124 = 5³ - 1. The next term should be 6³ - 1 = 216 - 1 = 215. But the given term is 217, which breaks this pattern. Therefore, 217 is the odd term that doesn't belong in the sequence.
