Andrea is designing the seating arrangement for a concert in her local park. To give everyone a good view, each row must have 4 more seats than the row bedore it and the 1st row can only have ten seats. Help Andrea plan the rest of the seating by solving for how many seats are in row 20. Then explain to Andrea how to create and equation to predict the number of seats in any row. Show your work, and use complete sentences.
