Jeff is designing the seating arrangement for a concert in his high school theater. To give everyone a good view, each row must have 5 more seats than the row before it, and the 1st row can only have 12 seats. Help Jeff plan the rest of the seating by solving for how many seats are in row 25. Then explain to Jeff how to create an equation to predict the number of seats in any row.

n = 12+5(n-1)
Where n is random number, the row will have 12 seats plus 5 for every row higher than 1.

So row 25 will have 12 + 5*(25-1)
12+24*5=12+120=132
Row 25 will have 132 seats.
