Answer:
A) 800 seats
Step-by-step explanation:

is the number of terms,
is the first term, and
is the last term
Therefore, substituting
,
, and
, we get:
![S_n=25(\frac{20+44}{2}),\\s_n=25\cdot 32=\boxed{800}](https://tex.z-dn.net/?f=S_n%3D25%28%5Cfrac%7B20%2B44%7D%7B2%7D%29%2C%5C%5Cs_n%3D25%5Ccdot%2032%3D%5Cboxed%7B800%7D)
