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.
Number of Cartons | Number of Cartons × 6 Eggs
[in each carton] | Total Number of Eggs |
1 | 1 × 6 | 6 |
2 | 2 × 6 | 12 |
3 | 3 × 6 | 18 |
4 | 4 × 6 | 24 |
So, Mandy could count 6, 12, 18, 24, and so on.
