    How to calculate Expected return for a series of probabilities.

    Hello,

    This is about roulette project on which I am working for a while and can't figure out a formula:

    the original table which describes this problem visualy is located at this Martingale: double after every loss system
    At the end of this table are general formulas, but my problem are last 3 colums of this table named E, F and G ("Average bet", "Bet units" and "Player edge")
    this formulas are ok for system where we double a bet each time after loose, but how do I calculate this when raising a bet 3 or more times each turn?

    this is formula 1-2npn
    where n = number of loost spin
    and p = initial probability to loose


    I need a formula similar to this so that it will calculate the case when doubling 4 times or more times per spin.
    also equation G=F/E must match


    thank you!
