A number pattern is a list of numbers that follows a certain rule.
Identify the rule of the pattern.
Each number in the pattern is 3 more than the number before it.
| 33 + 3 | = | 36 |
| 36 + 3 | = | 39 |
| 39 + 3 | = | 42 |
| 42 + 3 | = | 45 |
So, the rule is add 3.
To find the next two numbers in the pattern, add 3 to 45, and then add 3 again.
The next two numbers in the pattern are 48 and 51.
Use multiplication to count groups of 6.
