Definition
A sequence of real numbers is simply a function 
. For instance, the function 
defined on 
corresponds to the sequence 
.
Convergence
Intuitively, a sequence converges if its terms approach a particular number.
Formally, a sequence 
of reals converges to 
if and only if for all positive reals 
, there exists a positive integer 
such that for all integers 
, we have 
. If converges to 
, is called the limit of and is written 
.
