Answer:
19.9 miles
Step-by-step explanation:
In this problem we have:
is the distance travelled during the 1st day
is the distance travelled during the 2nd day
is the distance travelled during the 3rd day
is the distance travelled during the 4th day
We notice that the difference between the distance travelled on the (n+1)-th day and the distance travelled on the n-th day doubles every day. In fact:

Which can be rewritten using the general formula:

This means that

By applying this formula recursively, we can find the 7th term, which is the distance travelled on the 7th day:

So, the distance travelled on the 7th day is 19.9 miles.
The best way to remember which place is rounded to the nearest 10th, 100th, 1000th, etc., is by counting the number of 0's.
This question wants you to round to the nearest 10th.
How many 0's does 10 have? 1.
So we round one space after the decimal.
This gets us 73.2
