Name:    Lesson 4 - Comparing Expressions

1.

Complete the following table using the rule “Start with the number 3 and add 5 each time.”

 Column 1 Column 2 0 3 1 2 3 4

2.

Select the expression that can be used for the pattern rule from question 1.
 a. 5n b. 3n + 5 c. 3n d. 5n + 3

3.

Complete the following table using the rule “Start with the number 4 and add 5 each time.”

 Column 1 Column 2 0 4 1 2 3 4

4.

Select the expression that can be used for the pattern rule from question 3.
 a. 4n + 5 b. 5n + 4 c. 4n d. 5n

5.

Complete the following table using the rule “Start with the number 3 and add 2 each time.”

 Column 1 Column 2 0 3 1 2 3 4

6.

Select the expression that can be used for the pattern rule from question 5.
 a. 3n b. 2n + 3 c. 3n + 2 d. 2n

7.

How did the expressions from question 2 and question 4 change when the starting number changed?

8.

How did the expressions from question 2 and question 6 change when the amount added each time changed?

9.

The expression for the pattern rule for this cube pattern is 4n + 1.

What would the new expression be if the starting number changed to 5?
 a. 5n + 1 b. 5n c. 4n + 5 d. 5n + 4

10.

The expression for the pattern rule for this cube pattern is 3n + 2.

What would the new expression be if the amount being added each time changes to 7?
 a. 7n + 3 b. 3n + 7 c. 7n d. 7n + 2
