Students will review:
This chapter helps students review the concepts in a sequences and series unit of a standard math course. Topics covered include:
- Summation notation
- Arithmetic series
- Geometric series
- Arithmetic sequences
- Geometric sequences

1. What is a Mathematical Sequence?
A mathematical sequence is a set of numbers that makes a pattern and can be simple or complicated, finite or infinite. Explore sequences, terms in a sequence, and the different kinds of mathematical sequences, including the famous Fibonacci sequence.

2. How to Find and Classify an Arithmetic Sequence
Arithmetic sequences, the pattern of progressing numbers, can be classified by finding the difference between numbers in the sequence and then notating them into a formula. See the process of the two standard formulas used, as well as how to find them using terms.

3. Finding and Classifying Geometric Sequences
Geometric sequences are made by multiplying numbers together in a specific and repeated pattern. Learn about the ways geometric sequences are classified and how to find geometric sequences using the terms of any two given entries.

4. Summation Notation and Mathematical Series
Summation (sigma) notation is the key rule that indicates the sequence of a mathematical series within the start and end terms. Learn more about how summation notation is used to build and break down the formula of a mathematical series.

5. How to Calculate an Arithmetic Series
An arithmetic series is the sum of the individual numbers contained in an arithmetic sequence. Learn the differences between arithmetic series and arithmetic sequence and discover how the formula for arithmetic series can be applied to real-life scenarios in the Michigan Stadium Solution.

6. How to Calculate a Geometric Series
A geometric series is found by combining the numbers found in the sequence, seen through a formula. See the proof behind this formula and how it can be solved, even when using an infinite series.

7. Arithmetic and Geometric Series: Practice Problems
A mathematical series is composed of numbers added infinitely and these series can be classified as arithmetic or geometric. Learn about arithmetic and geometric series, and explore how each series differ from one another with four practice problems.
