🔍 Explanation:
Each sequence follows a consistent
arithmetic pattern (adding a fixed number). To solve:
1. Look at the difference between consecutive numbers.
2. Apply that same difference to find the next numbers.
These are great for building number sense and understanding basic arithmetic sequences! 🎯
Parent Tip: Review the logic above to help your child master the concept of patterns worksheet grade 5.
