    prime numbers

    Problem:
    n^2 + n + 41 = a prime number

    where n = 0, 1, 2, 3, 4, .... (any positve integer)

    Show that this is untrue without doing any calculation.

    I think:
    It has something to do with odd and even but after playing around with this idea can't find a solution.....help
