On the ticket website, there is a diagram of the seating arrangements. Every road that she checks out has exactly 4 more seats in the row that is directly in front of it. The first row is selling out fast as it only has a total of 10 spots. As she goes back from the front row back, she sees that there are 20 rows total. Without just writing out each of the numbers representing each row, create an actual equation that can show with the number of spots in a row would be using an Iterative formula.
