Additional Resources:

In this lesson, we will learn about the arithmetic sequence, which is also known as an arithmetic progression. An arithmetic sequence is a sequence where each term of the sequence after the first is found by adding some fixed number to the previous term. The fixed number is known as the common difference. We will use a lowercase "d" to show the common difference. Additinally, we will learn how to work with an arithmetic series.
