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 5 more than the number before it.
15 + 5 | = | 20 |
20 + 5 | = | 25 |
25 + 5 | = | 30 |
30 + 5 | = | 35 |
So, the rule is add 5.
To find the next number in the pattern, add 5 to 35.
The next number in the pattern is 40.
