The first six terms are $\frac{1}{2}$, 1, 1$\frac{1}{2}$, 2, 2$\frac{1}{2}$, and 3.

Work Step by Step

$a_{n}$=$\frac{1}{2}$n $a_{1}$=$\frac{1}{2}$(1) =$\frac{1}{2}$ $a_{2}$=$\frac{1}{2}$(2) =1 $a_{3}$=$\frac{1}{2}$(3) =1$\frac{1}{2}$ $a_{4}$=$\frac{1}{2}$(4) =2 $a_{5}$=$\frac{1}{2}$(5) =2$\frac{1}{2}$ $a_{6}$=$\frac{1}{2}$(6) =3 *To find a certain term, plug the number of the term you are looking for into the 'n' and solve.
