The next term is:
5140AAAA
The terms in the sequence are:
A series of guesses in the game Mastermind. The number is the guess, the letters indicate how close the guess is to the hidden sequence: A represents a correct number in the correct position, B represents a correct number but not in the correct position. Since the letters for the last guess are AAAA, the last guess must be the hidden sequence.
