Finite Difference

    Hello there...I'm currently stuck with a problem regarding finite differences. The question asks for me to come up with an equation to find the constant of the finite difference. An example would be...Let's take the equation y=10x^4 and the constant is 240. Any hints as to where to start or anyone feeling generous enough to just give me the equation? o:)

    well, I don't have any proof of this in hand but you could notice that
    10 * 4 * 3 * 2 * 1 = 240

    I think what you are doing is finding repeated differences:

    x f(x) [itex]\Delta x[/itex] [itex]\Delta^2 x[/itex]
    1 10 150
    2 160 640
    3 810 1750 1940
    4 2560 3690
    5 6250

    Thank Orthodontist and HallsofIvy, I think Ortho is on the right track...Still having a problem with coming up with an equation.
