Sequence

In this video, you’ll explore what a sequence is and how it helps us understand patterns in mathematics. We’ll define sequences formally, look at different types (such as arithmetic and geometric), and learn how to write formulas for them using explicit and recursive definitions.

By the end of this video, you’ll be able to:

Understand the difference between a sequence and a list of numbers
Identify whether a sequence is increasing, decreasing, bounded, or constant
Use notation like a_n and general terms
Recognize convergence and divergence of sequences
Work through several examples and build your intuition

This is the foundation for everything we’ll do with infinite series, so let’s start by building a strong understanding of sequences!
