Answer

$45+n$

Work Step by Step

Let us call the other number $z$. Since the difference of the two numbers is $45$, and the word "difference" indicates subtraction, we can write the following equation: $z-n=45$ We must solve the equation for $z$. To do so, we add $n$ to each side of the equation: $z=n+45$ Since the number we want to find is equal to $z$, the number is $45+n$
