Solution

Find the first three terms of the sequence $a_{n} = 5 n + 3$ by substituting $n = 1, 2, 3$ :
$\begin{array}{rcl} \Rightarrow & a_{1} = 5 \times 1 + 3 \\ = & 8 \end{array}$
$\begin{array}{rcl} \Rightarrow & a_{2} = 5 \times 2 + 3 \\ = & 13 \end{array}$
$\begin{array}{rcl} \Rightarrow & a_{3} = 5 \times 3 + 3 \\ = & 18 \end{array}$
The first three terms of the sequence $a_{n} = 5 n + 3$ is $8, 13, 18$ .
