Geometric sequences

Ahhhhh! It's that time of year when you hear RUMORS of students actually being enrolled in your classes, but you have scattered evidence. If it's not sickness, it's field trips or EOC exams or fill-in-the-blank reasons. Or if they ARE in class, some of them are NOT in class. If you know what I mean. Welcome to my Precalculus preAP experience. Because of this, I was trying to give this recently-absent child a run down of all things Sequences and Series. I sketched the following roughly on…
