This course contains 6 segments:

Introduction to arithmetic sequences

Learn about arithmetic sequences and their main features, the initial term and the common difference. Evaluate arithmetic sequences.

Constructing arithmetic sequences

Learn how to find the explicit or recursive formula of an arithmetic sequence.

Introduction to geometric sequences

Learn about geometric sequences and their main features, the initial term and the common ratio. Evaluate geometric sequences.

Constructing geometric sequences

Learn how to find the explicit or recursive formula of a geometric sequence.

Modeling with sequences

Now that we've mastered arithmetic and geometric sequences, let's see how they can help us solve real-world word problems. In this tutorial you will find the formula for a sequence that models a real-world relationship.

General sequences

Arithmetic and geometric sequences are very useful, but they are definitely not the only kinds of sequences out there. Let's zoom out and consider some other kinds of sequences.
