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:
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.
