Explanation

The series is 1! = 1, 2! = 2, 3! = 6, 4! = 24, 5! = 120, 6! = 720, 7! = 5040. The term 620 is incorrect; it should be 720.

AI explanation

The given series follows the factorial pattern where each term is the product of consecutive integers: 1x1=1, 1x2=2, 2x3=6, 6x4=24, 24x5=120, and 120x6=720. The correct term following 120 must be 720, which means 620 is the wrong term in the series.
