Understanding Numerical Patterns and Expressions

What is a rule in the context of numerical patterns?

• A consistent operation applied to an input to create an output

• A random operation applied to any number

• A mathematical equation with variables

• A number sentence with an equal sign

Which expression correctly represents the pattern with terms 5, 7, 9, and 11?

• 4x + 1

• 3x + 2

• 2x + 3

• x + 5

What is the first step in finding the expression for a pattern?

• Guessing the expression

• Using the input values to test expressions

• Adding all the terms together

• Subtracting the smallest term from the largest

Which expression fits the pattern with terms 8, 13, 18, and 23?

• 2x + 6

• 3x + 5

• 5x + 3

• 4x + 4

How do you verify if an expression fits a pattern?

• By comparing it to a different pattern

• By ensuring it works for all given input values

• By using it in a different mathematical operation

• By checking if it matches the first term only
