Martingale script, with a change?

Question

JavaScript

Kind people!!! can you tell me how to create a script with the following conditions?
The initial bet is 10, when you win it does not change, when you lose it increases by martingale(10, 20, 40, 80....), we play until there are 2 wins in a row at odds. 1.5, example: (lost 10, lost 20, lost 40, lost 80, won two bets of 160, and resets back to 10) and so on in a circle

Answer 1

Answer 2

If odds of 1.5 means that the win at a bet of 10 is only 15, then it is very difficult to win.
