How to calculate multiplication on martingale?

[Osmw]

Hi,

 

I went know how to calculate the percentage to recover loss in the martingale strategy (For exemple, if I have 50% chance to win and a win give me x2, if I lose I multiply by 100%) . In the Internet I don't find that so I hope somebody know.
