Elements in Number Patterns

The video tutorial explains number patterns, starting with a rule to add 7 to find the fifth element. It then presents an exercise to find the sixth element using a different rule: start with 2, multiply by 2, and subtract 1. The lesson concludes with a summary of how to find elements in number patterns.

What is a number pattern?

• A sequence of numbers following a specific rule

• A list of numbers with no order

• A group of numbers that are all the same

• A random set of numbers

If you start with 7 and add 7 repeatedly, what is the fifth number in the sequence?

• 35

• 42

• 28

• 21

In the pattern starting with 7 and adding 7, what is the third number?

• 21

• 28

• 35

• 14

What is the rule for the pattern starting with 2?

• Multiply by 2 and subtract 1

• Multiply by 2 and add 1

• Add 2 and subtract 1

• Add 2 and multiply by 1

What is the sixth number in the pattern starting with 2, multiplying by 2, and subtracting 1?

• 31

• 32

• 33

• 34
