Test questions: Growing numerical patterns (multiplication & division) Grade 4

📚 Quick Study Guide

🔢 Growing Numerical Patterns (Multiplication & Division): These patterns involve sequences where each number is found by multiplying or dividing the previous number by a constant value.

➕ Multiplication Patterns:
• ✖️ A sequence where each term is multiplied by the same number to get the next term. Example: 2, 4, 8, 16... (multiply by 2 each time)
• 🧐 To find the pattern, divide any term by the term before it.

➗ Division Patterns:
• ➗ A sequence where each term is divided by the same number to get the next term. Example: 81, 27, 9, 3... (divide by 3 each time)
• 💡 To find the pattern, divide any term before it by the term.

📝 Key Steps to Solve:
• 🔍 Look at the numbers and determine if they are getting bigger (multiplication) or smaller (division).
• ➗ Try dividing or multiplying consecutive terms to find the constant factor.
• ✏️ Use the factor to continue the pattern.
