Imagine building a tower with 2 toy blocks, then 4 blocks, and then 6 blocks! Every time you build, your tower gets taller.
This is called a growing pattern because the numbers get bigger in a steady way.

How do we crack the secret code behind these climbing numbers?
Finding the Pattern Rule
To find the pattern rule, count how many you must add to get from one number to the next.
Look at the numbers 3,6,9. Start at 3 and count up to 6: 4,5,6 — that is 3 more!

Once you know the rule, how do you find the mystery number that comes next?
Finding What Comes Next
To find the next term, add the rule amount to the very last number you have.
In our pattern 3,6,9, the last number is 9. Add 3 more: 9+3=12.
