defined on the natural numbers

I would like to change this:

"Formally, given any set X, an infinite sequence is a function (f, say) defined on a subset of natural numbers with values in X. "

to this:

"Formally, given any set X, an infinite sequence is a function (f, say) defined on the natural numbers $\{1,2,3,...\}$, with values in X. "

(I'm not sure whether to include zero in the natural numbers.) --Catherine Woodgold 08:12, 28 April 2007 (CDT)

Simple example?

This is given as a "simple example" of a sequence of complex numbers:

$1+i,2-5i,5-2i$

How about a simpler example, where it's easy to predict the next term? e.g.

$1+i,2+3i,3+5i$
