A theater has 30 rows of seats. There are 22 seats in the first row, 26 in the second row, 30 in the third row, etc. How many people will the theater hold ?

Arithmetic Sequence

rows 32-n

first term 26a

d4

Sn = n/2( 2a+(n-1)d)

=32/2 (2*26+(31)4)

=16(52+124)

=16(176)

=2816 seats

Total rows of seats, n = 30 rows of seats

First row, A1 = 22 seats

Second row, A2 = 26 seats

Third row, A3 = 30 seats

d = A3 - A2 = A2 - A1 = 4

then,

Sn = n/2 (2A1 + (n - 1)d)

Sn = 30/2 (2*22 + (30 - 1)4)

Sn = 15(44 + 116)

Sn = 2400 people

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?
