1. When recovering from shoulder surgery, Shelly is advised by her physical therapist to begin her
therapy with 10 slow arm circles. Every time they have a physical therapy session, she should increase
the number of arm circles by 4. Write a sequence that models the number of arm circles she will do at
her first 5 sessions. Then write an equation that represents how many arm circles she will do at session
n. Finally, if she follows her physical therapist's advice, how many arm circles will she do at her 25th
session?
