Lesson Summary:

In this lesson, you will learn how to recognize patterns and find equations to describe them. You will also learn how to predict future terms in a sequence based on your equation. Through various examples, you will see how to identify patterns and write rules to describe them. These examples include toothpick squares, algebra tiles, and dot patterns. By the end of this lesson, you will have a better understanding of how to recognize and write equations for patterns.

Lesson Description:

Learn how to recognize patterns and how to find an equation to describe the pattern. Also, you will learn how to predict future terms in a sequence based on your equation.

    This video does a great job of going through three different, separate problems and showing the thinking process for how to write out the terms, how to find the pattern, how to generalize the pattern with an equation, and how to find a future term in the sequence using the equation. This is a great tutorial for any beginning Algebra student.
