# Sequences

This topic covers: - Recursive and explicit formulas for sequences - Arithmetic sequences - Geometric sequences - Sequences word problems

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.
