Why is this distribution referred to as a geometric distribution?

The geometric distribution is:

Pr(X=k) = (1-p)k-1p for k = 1, 2 , 3 ...

A geometric series is a+ ar+ ar2, ... or ar+ ar2, ...

Now the sum of all probability values of k = Pr(X=1) + Pr(X = 2) + Pr(X = 3) ...

= p + p2+p3 ... is a geometric series with a = 1 and the value 1 subtracted from the series.
