Students, working in a group, are given a sheet of arithmetic and geometric sequences and asked to find a formula for the sequences and the value of the 55th term of the sequences. An answer is already given; they are to determine whether or not the given answer is correct.
Then, starting with $1000, students bid on problems they agree had the correct answer. The object of the auction is to win the most correct answers. At the end of the game, students share their solutions to the problems that had incorrect answers.
