๐ Topic Summary
Patterns and rules are the foundation of many mathematical concepts. They help us understand relationships between numbers and predict what comes next. In Grade 8, we often deal with linear patterns (where the difference between terms is constant) and rules expressed as algebraic equations. Mastering these concepts is essential for success in algebra and beyond. This quiz will test your understanding of identifying, extending, and expressing these patterns.
