Answer: 17.928666
Step-by-step explanation:
Radius is half of the diameter so the radius of 4 is 2
Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
Answer:
Step-by-step explanation:
it is not a function because -2 has two y values
