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.
