To solve the inequality \( 28 > 4n \), we first rearrange it to isolate \( n \).
1. Divide both sides by 4:
\[
\frac{28}{4} > n
\]
This simplifies to:
\[
7 > n
\]
or equivalently,
\[
n < 7
\]
Thus, the possible values of \( n \) are all real numbers less than 7. In interval notation, this can be expressed as:
\[
(-\infty, 7)
\]
So, all possible values of \( n \) are \( n < 7 \).
