Aman will swim 3.03.0 miles on Saturday.

Explanation:

Look at the numbers in a sequence.

1.5, 1.6, 1.8, 2.1, 2.51.5,1.6,1.8,2.1,2.5

Determine the change from each term to the next.

+0.1, +0.2, +0.3, +0.4+0.1,+0.2,+0.3,+0.4

As you can see, the next term will be equal to 2.5 + 0.52.5+0.5, or 3.03.0.
