    The situation described above is an example of a geometric sequence. The common ratio is 1/2 and the initial term (a1) is 128. The second term of the sequence is the number of teams left after a week. Hence, the number after six weeks is the 7th term. To solve for the 7th term,

    a7 = a1 x r^ (n - 1)

    a7 = (128) x 0.5^ (6) = 2

    Thus, only 2 teams remain after 6 weeks.
