Answer
$a_1=2\\ a_2=5 \\a_3=8 \\a_4=11 \\ a_5=14$
Work Step by Step
We are given that $a_n=3+a_{n-1}$ and $a_1=2$. In order to determine the remaining values, we will have to substitute $n=2,3,4,5$ into the given sequence. Thus:
$a_2=3+a_1=3+2=5 \\a_3=3+a_2=3+5=8 \\a_4=3+a_3=3+8=11 \\ a_5=3+a_4=3+11=14$
