AI explanation

The pattern multiplies each term by an increasing integer and then adds or subtracts a sequentially changing number. The logic should be 5 times 2 plus 4 equals 14, 14 times 3 plus 2 equals 44, and 44 times 4 minus 1 equals 175. Continuing forward, 175 times 5 minus 2 equals 873, and 873 times 6 minus 3 equals 5235, meaning the correct terms for the series should start with 5, 13, 44, and so on, so the intended logic is multiply by 2 plus 3 equals 13, making 14 the wrong term.
