It says:

We can use the definition of the convergence of a sequence to define the sum of an infinite series as the limit of its sequence of partial sums. Let(x

_{n}) be a sequence of ℝ. The sequence of partial sums (x

_{n}) of the series ∑(x

_{n}) is defined by s

_{n}= ∑x

_{k}from k=1 to n.

I just need someone to explain to me how an infinite series is the limit of a sequence of partial sums.
