# Sequences

Contents

You may have learned about sequences before. Sequences serve as the foundation for series, which are really important in integral calculus. Review you knowledge of sequences right here.

In this tutorial, we'll review what sequences are, associated notation and convergence/divergence of sequences.

Now that we understand what a sequence is, we're going to think about what happens to the terms of a sequence at infinity (do they approach 0, a finite value, or +- infinity?).
