5

step-by-step explanation:

Answer is negative 2

answer: - (a)[tex]a_n=16+6n[/tex]

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term= [tex]a_1 =22[/tex]

second term= [tex]a_2 =28[/tex]

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula : [tex]a_n=a_1+(n-1)(d)[/tex]

[tex]a_n=22+(n-1)6\\\rightarrow\ a_n=22+6n-6\\\rightarrow\ a_n=16+6n[/tex]

b) let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

[tex]a_{12} = 16+6\times12\\\rightarrow\ a_{12}=16+72\\\rightarrow\ a_{12}=88\ seats[/tex]

∴there are 88 seats in 12 rows.
