Hi! Let's explore number sequences together. Patterns are like secret codes!
A sequence is an ordered list of numbers. The numbers follow a special rule.
Let's analyze how the numbers change from one step to the next. Look closely at 2, 4, and 6. We add 2 each time!
When you find the rule, you can predict what comes next. Adding 2 to 6 gives us 8!
✏️ Worked example
Analyze the sequence to find the missing number: 3, 6, 9, __.
- First, look at the first two numbers: 3 and 6.
- Compare them: 3 + 3 = 6. The pattern might be add 3.
- Check the next pair: 6 + 3 = 9. The rule is definitely add 3!
- Apply the rule to 9: 9 + 3 = 12.
- The missing number is 12!
