I am doing a practice test for Algebra 2 and I don't know how to solve it. Word problems always get me 
. I don't know what function to use or what information to plug in. The question is:
Andrea is designing the seating arrangement for a concert in her local park. To give everyone a good view, each row must have four more seats than the row before it, and the first row can only have 10 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 an equation to predict the number of seats in any row. Show your work, and use complete sentences.
May you please help me?
