1. In a concert hall, the number of seats in each row increases as you move farther from the stage. There are


the first row, 38 seats in the second row, and 45 seats in the third row.


a) If this pattern continues, determine what type of sequence this represents. Then write a function rule in simplified


form that can be used to find the number of seats in the nth row. Be sure to use the correct notation you have


learned this unit. Show ALL work.


b) Use the rule to determine which row has 290 seats. Show ALL work.
