    You call this a mathematical riddle...?

    This is a mathematical riddle.

    Let (an) be a sequence defined as follows: a1 is a positive integer and an = int((3/2) × a(n-1)) + 1, where int = rounding down to the next smallest integer.

    Is it possible to choose a1 such that a100001 is odd and an is even for n < 100001 ?

    Since x is also the price of the game, 10 + .5x must equal x.

    So, 2(10 + .5x) = x(2)

    20 + x = 2x
    x = 20
    though why'd you pick 2 mmz

    You mean why did I multiply by 2?
    It was to get rid of the ugly decimal/fraction on the left side.

    ehh idk, i didn't like math.
    i think it's coming back, multiply by 2 to rid of a variable on both sides of an equation, yes?

    To get rid of 0.5x
    It's actually optional:
    10 + 0.5x = x
    10 = 0.5x
    10/(1/2) = x
    10 * 2 = x
    x = 20
