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:
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!
Do your students focus on number pattern (sequences) instead of variable relationship (function)? Mine too! Let's use their tendencies to our advantage when teaching arithmetic and geometric sequences as function models in Algebra 1 or Algebra 2. This bundle includes investigations and cooperative learning activities to connect sequences and functions while prompting students to write explicit and recursive formulas to model situations.
