Arithmetic Patterns

The elf in charge at Santa’s workshop kept track of how many toys Buddy the Elf made in the table shown. He noticed Buddy made the same amount of toys every hour. Fill in the missing value for 5 hours.

• 16

• 15

• 20

• 25

What is the rule for the pattern you used to find the missing value?

• Add 3 to the input number

• Multiply 2 to the input number

• Multiply 3 to the input number

• Add 1 to the input number

Continue the pattern:

50, 45, 40, ____, ____, ____

• 45, 50, 55

• 30, 20, 10

• 35, 40, 45

• 35, 30, 25

50, 45, 40

What is the rule for this pattern?

• Starting at 50, subtract 5

• Starting at 0, add 5

• Starting at 50, add 5

• Starting at 50, subtract 10

The table shows a pattern between the input and output values. What are the missing values in the table?

• a = 6

  b = 27

  c = 30

• a = 6

  b = 27

  c = 32

• a = 6

  b = 28

  c = 32

What is the rule to this input/output table?

• Multiply the input number by 5 to calculate the output number

• Divide the input number by 5 to calculate the output number

• Divide the input number by 4 to calculate the output number

• Multiply the input number by 4 to calculate the output number

The table shows a pattern between the input and output values. What are the missing values in the table?

• a = 14

  b = 10

  c = 6

• a = 14

  b = 6

  c = 10

• a = 15

  b = 6

  c = 11

What is the rule for this input/output table?

• Divide the input number by 2 to calculate the output number

• Multiply the input number by 2 to calculate the output number

• Subtract 1 from the input number to calculate the output number

Choose the number pattern that follows this rule.

Rule: Starting at 16, multiply by 2

• 0, 4, 8, 12, 16, 20

• 16, 18, 20, 22, 24

• 16, 32, 64,128, 256

• 16, 14, 12, 10, 8
