Number Line Patterns and Sequences

The video tutorial explains how to use a number line to identify a pattern in a sequence of numbers: 7, 27, 47, 67. The instructor marks these numbers on the line and demonstrates that the pattern involves adding 20 to each number to find the next in the sequence. This pattern is applied to predict the next number, 87, by adding 20 to 67.

What is the purpose of using a number line in this math problem?

• To subtract numbers

• To multiply the numbers

• To find the sum of the numbers

• To identify a pattern in the sequence

How many numbers are there between each marked point on the number line?

• 5

• 20

• 15

• 10

What is the pattern observed in the sequence of numbers?

• Multiplying by 2

• Subtracting 10

• Adding 15

• Adding 20

If the pattern continues, what number comes after 67?

• 97

• 107

• 87

• 77

What is the result of adding 20 to 67?
