You can put this solution on YOUR website! "A theatre has 25 seats in the first row and 35 rows in all. Each successive row contains one additional seat. How many seats are in the theater?"
---------------------------
Arithmetic Series with a(1) = 25 and d = 1
--------
S(n) = a(1) + (n-1)d
-----
S(35) = 25 + 34*1 = 59 seats
