Answer: The required expression is
n-3.

Step-by-step explanation: We are given to write an expression for the following statement :

"n decreased by 3."

We know that

if we are decreasing a units from some quantity b, then we should subtract a from b.

This is written as follows :

E=b-a.

Therefore, for the given expression, we should subtract 3 from n.

This can be written as :

E=n-3.

Thus, the required expression is
n-3.
