The sequences are classified, respectively, as:
Geometric, Arithmetic, Neither.
<h3>What is a geometric sequence?</h3>A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
In the first sequence, we have that:
Hence it is a geometric sequence.
<h3>What is an arithmetic sequence?</h3>In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
In the second sequence, we have that:
d = -4 - 1 = 1 - 6 = 6 - 11 = 11 - 16 = -5
Hence it is an arithmetic sequence.
<h3>What about the third sequence?</h3>Hence it is neither arithmetic nor geometric.

2. The area for a circle is as follows:
A = π
The radius of the circle is 4 in, so we plug that into the equation.
A = π (4
)
4 = (4 in.)(4 in.) = 16
A = 16π
This is the area for the whole pizza, so divide that by 2 to get the area of the pepperoni
a) 8π
For the bacon, we can just divide the value we already have by 2, since it is half the area of the pepperoni
b) 4π
3. This question is asking for the circumference, whose equation is as follows:
C = 2 π r
We can use the area formula, A = π to find the radius of this circle
36π = π
Divide both sides by π:
36 =
Square root both sides:
r = 6 in.
Plug in this value to the circumference formula, C = 2 π r
C = (2)(π)(6 in.)
Your final answer is:
C = 12π in.
A = π

Answer:
Step-by-step explanation:
First, you should distribute the -1 on the right.
Next, add 8n to both sides. This should cancel out the 8n.
Now, add 8 to both sides. This will get n by itself.
Your answer is n = -2.
