    If each team plays with each of the other four teams N times, then the number of games played would be:
    4, 8, 12, ...
    Can you find which of the five numbers does not belong?

    So its 8?

    Obviously you did not read MathMate's answer.

    Oh 14?

    Right.

    14 is the only number that is not a multiple of 4.
