Chapter Overview

This chapter teaches Pattern Rules, Predictions, and Missing Elements in original, simple language with step-by-step reasoning, worked examples, practice exercises, common mistakes, and review questions.

32.1 Writing a pattern rule in words

A pattern follows a predictable rule. Repeating patterns repeat a core; growing patterns change in a consistent way. Work one step at a time, use a model or number sentence when useful, and check whether the answer is reasonable.

Beginner Explanation

First identify what is given and what must be found. Then choose a strategy, show the steps clearly, and check the final answer.
