Answer:

Explanation:
Here, we want to get the sequence type
In an arithmetic sequence, the difference between terms is the same
For a geometric sequence, the division of a succeeding term by a preceding term would yield the term called the common ratio
Now, let us consider the differences:

This means that the sequence is not arithmetic
Now, let us test if geometric
Mathematically, we have that as:

This means that the given sequence is geometric
Runner = 5 mph
bicyclist...4 times the runner....4(5) = 20 mph
20 - 5 = 15 mph <== the difference
Answer:236,520 hours
Step-by-step explanation:
You multiply the years(27) times the number of days in one year(365) which equals 9,855 and then you multiply that by the number of hours in a day(24) so it equals 236,520.
