Test questions: identifying the relationship in growing number sequences (Grade 4)

🔢 Quick Study Guide

• ➕ Identifying Growing Number Sequences: Growing number sequences increase by a consistent rule or pattern.
• 🔍 Finding the Pattern: Look for the difference between consecutive numbers. This difference is often the 'rule'.
• 💡 Addition Rule: The most common pattern in Grade 4 is adding the same number each time (e.g., 2, 4, 6, 8... adds 2 each time).
• 📝 Multiplication Rule: Another pattern could involve multiplying by the same number (e.g., 1, 2, 4, 8... multiplies by 2 each time).
• ➕ Mixed Operations: Sometimes, a sequence may involve a combination of addition and multiplication, but for Grade 4, focus on simpler additive patterns.
• ➗ Checking Your Answer: Always double-check that the rule consistently applies to all numbers in the sequence.
