4.03 Number machines
Lesson
Are you ready?
You may have already seen some patterns, try this one.
Write the next number in the pattern:
$1$1, $3$3, $5$5, $7$7, $9$9, $11$11, $\editable{}$
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 $8$8 $\editable{}$ $9$9 $\editable{}$ $10$10 $\editable{}$
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.
