a. an = -17 + 4(n + 2)
b. an = -17 x 4(n - 1)
c. an = -17 + 4(n - 1)
d. an = -17 + 4(n + 1)

do your own work and don"t cheat.

step-by-step explanation:

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

answer: - (a)

(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=

second term=

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

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

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

∴there are 88 seats in 12 rows.
