Ernest would be swimming at 3.25 units on week 10
The explicit formula is given as:

Also, we have the following parameters
-- the initial distance
--- the difference between concurrent distances
In week 10, the value of n is 10.
Next, substitute 10 for n in the explicit formula 
So, we have:

Subtract 1 from 10

Multiply 9 by 0.25

Add 1.0 and 2.25

Hence, Ernest would be swimming at 3.25 units on week 10
