how do i prove this is a geometric series?

look at the definition of a geometric series, and try to see how this example satisfies it.

The ratio between two terms of the sequence is always [tex]\left( {1 + i} \right)[/tex], a constant, just what we need for a geometric sequence -> this gives of course a geometric series.
