Answer:

12.5 miles

Explanation:

We can observe that the distance biked is increasing by 0.3 miles on the second day, then by 0.6 miles on the third day, and finally by 1.2 miles on the fourth day.

This means that the increment in distance is increasing by 0.3 miles each day. Therefore, the distance biked on the seventh day can be calculated as follows:

On the fifth day, you will bike 7.1 + 1.5 = 8.6 miles (increment of 1.2 miles).

On the sixth day, you will bike 8.6 + 1.8 = 10.4 miles (increment of 1.5 miles).

On the seventh day, you will bike 10.4 + 2.1 = 12.5 miles (increment of 1.8 miles).

Therefore, you will bike 12.5 miles on the seventh day if you continue this pattern.

Hope this helps!
