The number $n$ is $3.8$.

#### Explanation:

First, translate the English sentence to math. "Difference" means subtraction and "is" means equals. It will looks like this:

$\stackrel{n - 1.8}{\overbrace{\text{The difference between a number n and 1.8"" " stackrel(=) overbrace"is"" " stackrel2 overbrace"2.}}}$

Now solve for $n$ in the equation:

$n - 1.8 = 2$

Add $1.8$ to both sides of the equation.

$n - 1.8 + 1.8 = 2 + 1.8$

$n \textcolor{red}{\cancel{\textcolor{b l a c k}{- 1.8 + 1.8}}} = 2 + 1.8$

$n = 2 + 1.8$

$n = 3.8$

The number is $3.8$.
