Answer:
We can describe the 32 rows of
seat as an arithmetic sequence with a
common difference of 4 and first term of
26.
We can use the Arithmetic Series formula
to get the total number of chairs.
a1 26
d = 4
n = 32
$32 ?
$32 n/2 [2a1 + (n-1)d]
$32 32/2 [2(26) + (32-1)4]
s32 16 (52 +124)
$32 16 (176)
S32 = 2816
Therefore, the total number of seats is
2816.
