Ta có : \(3n-1⋮n-1\)
\(\Leftrightarrow3n-3+2⋮n-1\)
\(\Leftrightarrow3.\left(n-1\right)+2⋮n-1\)
\(\Leftrightarrow2⋮n-1\)
\(\Leftrightarrow n-1\inƯ\left(2\right)\)
Mà \(Ư\left(2\right)=\left\{1;-1;2;-2\right\}\)
\(\Rightarrow n-1\in\left\{1;-1;2;-2\right\}\)
\(\Rightarrow n\in\left\{2;0;3;-1\right\}\)
Vậy \(n\in\left\{2;0;3;-1\right\}\)
