It is D.
When you plug in the step number instead of "n" you need to get "a" for your answer.
inverse proportionality between 2 variables follows this .
y = k/x
where k is proportional constant
as value of one variable increases/decreases , value of other variable decreases/increases
so
if x increases, y will decrease
if x decreases , y will increase
All real numbers satisfy the equation, try plugging in a number into x and you'll find out
