Introduction_to_arithmetic_squences

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.

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.

Constructing_geometric_sequences

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

Introduction_to_geometric_sequences

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

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.
