Solution

\[\text{ We have }, 4x - 2 < 8\]
\[ \Rightarrow 4x < 8 + 2 (\text{ Transposing - 2 to the RHS) }\]
\[ \Rightarrow 4x < 10\]
\[ \Rightarrow x < \frac{10}{4} (\text{ Dividing both the sides by 4 })\]
\[ \Rightarrow x < \frac{5}{2}\] 

\[x \in N\]
\[\text{ Then, the solution of the given inequation is } \left\{ 1, 2 \right\} .\]
