Finding the 9th Step in a Geometric Pattern Using a Table

The video tutorial explains how to find the 9th shape in a geometric pattern using a table. It introduces the concept of steps and rules in patterns, emphasizing the importance of both the number of pieces and their arrangement. The tutorial demonstrates how to use a table to analyze pattern growth and apply rules, ultimately calculating the 9th step as a 9x9 square with 81 pieces.

What is the rule for the growth of the pattern in the first section?

• Subtract 1 at each step

• Multiply by 2 at each step

• Add 1 at each step

• Divide by 2 at each step

In the second section, what is emphasized as important when analyzing a geometric pattern?

• Only the number of pieces

• The color of the pieces

• Only the shape of the pieces

• Both the number and arrangement of pieces

What method is used to determine the number of pieces in each step of the pattern?

• Using a ruler

• Using a graph

• Using a table

• Using a calculator

How many pieces are there in the 9th step of the pattern discussed in the third section?

• 64 pieces

• 90 pieces

• 72 pieces

• 81 pieces

What shape do the pieces form in the 9th step of the pattern?

• A square

• A triangle

• A circle

• A rectangle
