🔍 Summary of Patterns:
All patterns are
arithmetic sequences where each term increases by a constant amount:
- Add 2 → odd/even numbers
- Add 10 → tens increasing
- Add 3, 5, etc. → multiples or skip counting
This helps students recognize and extend number patterns based on consistent differences between terms.
