Given the function, find the first four terms of the power series representation and find the domain of convergence?

function is;

(1-x)/(1-2x)^3

my calculation;

find derivatives of the function.

y'=(1-x)/(1-2x)^4

y''=(1-x)/(1-2x)^5

I am having difficulty in knowing if what I did was correct.

I'm not sure if this is how you are meant to approach it and if what I did was the correct way to go about solving the problem.

If anyone can help me in solving my problem your help will be appreciated.
