Number Sequences With 2 Rules Each box contains a number, and the numbers form a sequence or pattern. Each colored arrow represents a different rule.
Apply the correct rule to find the next number.
To complete this pattern you must start with the number in the first box, 25. The blue rule says to "add 5." Follow the rule, 25 + 5 = 30. Now you begin with 30. You must follow the green rule now. The green rule says to "subtract 10." Follow the rule, 30-10 = 20. Now you have 20. You must apply the blue rule, add 5. 20 + 5 = 25 Now you have 25. You must follow the green rule, subtract 10. 25 - 10 = 15 Now you have 15. You must follow the blue rule, add 5. 15 + 5 = 20 Now you have 20. You must follow the green rule, subtract 10. 20 - 10 = 10
