# Geometric Sequence Equation

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.

Students revisit linear and exponential scenarios through equations, tables and graphs. They will use horizontal shifts to create sequences with initial values at n=1. They will practice writing functions using sequence notation. Given selected values for a sequence, students will find the initial value, common difference or common ratio then write the formula for the sequence. They will use the formulae for finite series. This mission is aligned with Common Core State Standards: HSF.LE.A.2
