Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to find the z-tranform of the following equation: x(n) =-2^{n}u(-n-1)

Using the Z-transform definition,summation and geometric series

I am getting 1/(1-2z^{-1})

But according to my lecturer the answer is suppose to be 0.5/(1-2z^{-1})

I have tried simplification/factorization and still seems to be wrong.

Thanks
