1. You are raising money for Amnesty International at school. The club already has $100 before you start fundraising, and you raise an additional $50 per week. If you were to model this as a sequence would it be arithmetic or geometric? Why?
It would be arithmetic because you are increasing the answer by the same amount each week.
100, 150, 200, 250, 300, ...
This sequence has a common difference of 50.
