Arithmetic sequences have a common difference between consecutive terms.
Geometric sequences have a common ratio between consecutive terms.
Let's compute the differences and ratios between consecutive terms:
Differences:

Ratios:

So, as you can see, the differences between consecutive terms are constant, whereas ratios vary.
So, this is an arithmetic sequence.
Answer:
$ 12.09
Step-by-step explanation:
formula Y = KX
Where; y = $ 24.18
x = 2 books
k = constant of proportionality
Step 1. Do the equation based on the formula
Y = kx
$24.18 = k2
Step 2. Divide by 2
$24.18/2 = k2/2
k = $12.09 (answer)
Answer:
28.26ft
Step-by-step explanation:
A=πr^2
π*3^2=28.27433
28.26
M=-1/2 because you do y1-y2 over x1-x2 and end up with 2/-4 but simplified is -1/2
Answer:
27
Step-by-step explanation:
22 + 6 = 28 - 1 = 27
