## Lesson 1 - Patterns

This lesson is a fun, interactive and low key list of patterns. I give you the first few items in the pattern, and you tell me the next three. You will also need to tell me how you found those next three items in the list.

Here is a copy of the worksheet:

## Lesson 2 - Explicit and Recursive Formulas

In this lesson, we will learn the difference between explicit and recursive formulas for patterns. We will also write both formulas for each of the patterns.

## Lesson 3 - Writing Formulas

In this lesson, I give you pieces of patterns and you write an equation that will go with the pattern. The equations will mostly be linear and exponential.

## Lesson 4 - Arithmetic Sequences

In this lesson we will learn what Arithmetic Sequences are, what the formulas for the equations are, and write both the explicit and recursive equations for each sequence.

## Lesson 5 - Geometric Sequences

In this lesson we will learn what Geometric Sequences are, what the formulas for the equations are, and write both the explicit and recursive equations for each sequence.

## Lesson 6 - More Sequences

This lesson is a mid-chapter review. On this worksheet, you will write the equations for both geometric and arithmetic sequences. You will also find certain items in a sequence given pieces of information.

## Lesson 7 - Limits of Sequences

In this section we will discuss the vocabulary words converge and diverge. We will also learn if the sequences we are working with converge or diverge.
