AI explanation

The differences between the numbers are squares of consecutive odd numbers: 1 squared, 3 squared, 5 squared, 7 squared, and so on. The differences should be 1, 9, 25, 49, 81, and 121, meaning the sequence should be 10, 11, 20, 45, 94, 175, 296. The incorrect term is 104 because it should be 94.
