Objective
To identify and describe patterns
In the Solve It, you identified and used a geometric pattern. In this lesson, you will identify patterns in pictures, tables, and graphs and describe them using numbers and variables.
Essential Understanding You can represent some patterns using diagrams, words, numbers, or algebraic expressions.
Look at the figures from left to right. What is the pattern? What would the next figure in the pattern look like?
The pattern shows regular polygons with the number of sides increasing by one.
How can you identify a pattern?
Look for the same type of change between consecutive figures.
The last figure shown above has six sides, so the next figure would have seven sides. This is a heptagon: .
