**Steve**, Saturday, November 17, 2012 at 10:15pmSince the rows come in pairs, the sequence looks like

8 8 10 10 12 12 ...

SO, considering the nth pair of rows, they have 12+4n seats together.

In 24 rows, there are 12 pairs, so

the 12th pair has 12+48 = 60 seats

the sum is

12/2 (8+60) = 6*68 = 408 seats
