WebThe sequence is an arithmetic progression where a1 = 26 and d = 2. an = a1 + (n − 1)d = 26 + (n − 1) ⋅ 2 = 26 + 2n − 2 = 2n + 24 Therefore, the number of seats in each row is given by an = 2n + 24. To calculate the total seating capacity of the 18 rows we need to calculate the 18 th partial sum. To do this we need the 1 st and the 18 th terms:
