Students learn the explicit formula for geometric sequences through these doodle notes. Additionally, the sum of infinite and finite geometric sequences formulas are introduced with examples for practice. Doodle notes are a great way to activate the creative side of the brain while learning material that often just uses the logical side.
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.
