 Number and Number Sense Focus: Proportional Reasoning The student will describe and represent arithmetic and geometric sequences, using variable expressions. HCPS Course 2 Curriculum Guide
 Essential Knowledge and Skills Analyze arithmetic and geometric sequences to discover a variety of patterns. Identify the common difference in an arithmetic sequence. Identify the common ratio in a geometric sequence. Given an arithmetic or geometric sequence, write a variable expression to describe the relationship between two consecutive terms in the sequence. Essential Understandings When are variable expressions used? Variable expressions can express the relationship between two consecutive terms in a sequence.

1. Arithmetic Sequences: Find the value of individual terms in arithmetic sequences using graphs of the sequences and direct computation. Vary the common difference and examine how the sequences change in response.
2. Arithmetic and Geometric Sequences: Find the value of individual terms in an arithmetic or geometric sequence using graphs of the sequence and direct computation. Vary the common difference and common ratio and examine how the sequence changes in response.
3. Geometric Sequences: Explore geometric sequences by varying the initial term and the common ratio and examining the graph. Compute specific terms in the sequence using the explicit and recursive formulas.
