Answer:
B. -6
Step-by-step explanation:
The common difference here is the difference between each term. Since it is an arithmetic sequence the difference between each term will be the same value.
So, from 45 (the 1st term) to 39 (the 2nd term), the difference is -6
From 39(the 2nd term) to 33, the difference is also -6.
Therefore, we know that the common difference fro this arithmetic sequence is -6.

Step-by-step explanation:
Hello!
You run 5 miles a hour
To find how far you go in half an hour you divide the distance by 2
5 / 2 = 2.5
To find how far you go in 2 1/2 hours you multiply the distance by 2.5
5 * 2.5 = 12.5
The answers are 2.5 miles in half an hour and 12.5 miles in 2 1/2 hours
Hope this helps!
