I am stucked while plotting time discrete for the inverse z transfer.

I want to plot the time discrete sequence for the below transfer function:

F(z)=z/(z-0.5)(z-2)

I have written the below code. Though it's not showing any error, as per my understanding the result is not correct. Can anyone please help?

What do you thnk is incorrect about the result?

Hi,

By applying partial fraction to the z transform it gives

inverser transform gives , expandi this equation by changing the n values from 0 to inf or -inf to 0 depending on the stability and causality parameter

By expanding the values are matched exactly with the sequence.
