    You want the one sided z-transform of x_n=d^n,\ n=0, 1, ...\

    The z-transform of this is:

    \displaystyle \left(\mathcal{Z}(x_n) \right)(z)=\sum_{n=0}^{\infty} x_n z^{-n} \displaystyle<br />
=\sum_{n=0}^{\infty} \left(\frac{d}{z}\right)^n

    You should recognise the right hand side as a geometic series which converges when d<z and you should know how to sum that.
