Emmanuel is starting a cycling training program. He will start cycling a short distance and increase his distance over time. Emmanuel will cycle 5 miles during the first week and increase his distance by 2 miles each week for 12 weeks. The table shows his training plan for the first 7 weeks.

Create a recursive function that defines the number of miles Emmanuel will cycle during the nth week, where 2 ≤ n ≤ 12.
