Answer

Explanation:

Step1: Recall complement definition

The complement of a set $A$ with respect to a universal - set $U$, denoted as $A^{c}$, consists of all elements in $U$ that are not in $A$.

Step2: Identify elements in $U$ and $A$

Here, $U$ is the set of all positive integers, and $A$ is the set of all odd positive integers. So, the elements in $U$ that are not in $A$ are the even positive integers.

Answer:

$A^{c}={x|x\in U\text{ and }x\text{ is an even positive integer}}$
