Arithmetic Sequences
Identify arithmetic sequences by constant common differences and write explicit and recursive formulas. Calculate any term in a Grade 9 arithmetic sequence.
Key Concepts
New Concept An arithmetic sequence is a sequence that has a constant difference between two consecutive terms called the common difference . What’s next Next, you will learn the key formulas for describing these sequences. We'll use them to find any term and solve problems involving constant growth or change.
