In this lesson, you will learn how a function can be represented by two different equations. You will find any term of an arithmetic sequence directly, by using the nth term formula to find any term number .
When you finish this lesson, you will be able to:
- Describe the nth term.
- Find terms of sequences directly.
- Explain why different equations can represent the same sequence.
Here are the activities that will help you reach those goals:
- 4.18.1 Repeated Operations
- 4.18.2 Identifying Domain for a Function
