The common difference in an arithmetic sequence refers to the number that represents the difference between two terms in the sequence.
When you look to the sequence you can see that from a term to other one the numbers are increasing, meaning that the common difference needs to be positive. To find the value of the common difference in an arithmetic sequence you have to select two terms. On this case 2.5 and 6, and 16.5 and 20.
Common Difference= 6-2.5
Common Difference= 3.5
Common Difference= 20-16.5
Common Difference= 3.5
After some calculations, you can conclude that the number representing the common difference in this arithmetic sequence is 3.5.
Answer: The graph for x cubed has a steep incline levels for a little before another steep incline

Answer:
38.9 cubic yards
Step-by-step explanation:
We have been a new sidewalk will be 5 feet wide, 280 feet long, and filled to a depth of 9 inches (0.75 foot) with concrete. We are asked to find the amount of concrete required to make the side walk.
The amount of concrete required to make the side walk would be equal to the volume of the sidewalk.
We will use volume of cuboid formula to solve our given problem.
We know that .
Therefore, approximately 38.9 cubic yards of concrete are needed.
