Geometric sequences and series

Colleen Werner's lesson "Introduction to Sequences" Objective: SWBAT differentiate among arithmetic, geometric and other types of sequences and understand that sequences and series can be used to model real world phenomena. Big Idea: Detecting patterns in numbers helps students see the mathematical relationships that underlie real world phenomena. In this colorful lesson, students look at patterns of numbers and uncover the rule used to generate them.

This foldable provides an organized way of taking notes. It easily compares the rules and examples for arithmetic and geometric sequences.An answer key is included!This foldable is also included in The Ultimate Foldable Bundle for 8th Grade Math, Pre-Algebra, and Algebra 1!

Arithmetic, Geometric, or Neither?

The Golden Section

Using Algebra to Find the Sums of Sequences Algebra can help you add a series of numbers (the sum of sequences) more quickly than you would be able to with straight addition. Adding integers, squares, cubes, and terms in an arithmetic or geometric sequence is simple with these algebraic formulas:

Arithmetic Sequences and Series Foldables

Mrs. Hester's Classroom...arithmetic and geometric sequences

This activity requires students to determine if a given sequence is arithmetic, geometric, or neither (they will use colors to do this). After that they will then determine the common difference (for arithmetic sequences) or the common ratio (for geometric sequences).Two versions of this activity are included, version one just has students working with numbers in the sequences that are positive, whereas version two is more challenging since it has both negative and positive numbers in the…
