Answer:</h2>
<em>You will bike 30.2 miles in the seventh day according to the prediction.</em>
<h2>
Explanation:</h2>
Here we have the following data, You bike
- 5 miles the first day of your training,
- 5.4 miles the second day,
- 6.2 miles the third day, and
- 7.8 miles the fourth day.
So we can know some facts:
- From the first day to the second day the number of miles increases:

- From the second day to the third day the number of miles increases:

- From the third day to the fourth day the number of miles increases:

By taking a look at the pattern, we can see that each day you increases the number of miles by a factor of 2 compared to the previous day. So:
- From the fourth day to the fifth day the number of miles increases:

- From the fifth day to the sixth day the number of miles increases:

Finally:
- From the sixth day to the seventh day the number of miles increases:

The height should be 8 because the area of a triangle is b*h/2 so 6*8= 48/2=24 so the height is 8.
