Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
Circumference of a circle = 2 x pi x radius
C = 2 x pi x 3
C = 6 x pi
C = 18.84
(using 3.14 for pi)
