## Are you ready?

You may have already seen some patterns, try this one.

Write the next number in the pattern:

$2$2, $4$4, $6$6, $8$8, $10$10, $12$12, $\editable{}$

Just like when you're counting, patterns can continue forever. You can always add or subtract the same amount to continue a pattern.

## Learn

Let's look at how number machines can be used to continue patterns when you have the rule.

### Apply

Think about the following function machine:

Complete this table of inputs and outputs:

Input |
Output |

$6$6 |
$\editable{}$ |

$7$7 |
$\editable{}$ |

$8$8 |
$\editable{}$ |

Remember!

- Number machines show the relationship between the input (starting number) and output (answer).
- If you are given the output, you can find the input by reversing the rule.
