One way of writing this in set builder notation could be:
Which can be interpreted as:
The set A is the set of any x such that 2≤x≤8 such that half of x is a natural number (N).
There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e. ∈,|,N), it becomes much easier to “read as a sentence”.
Here are a few more ways of writing the set A=2,4,6,8 in set builder notation:
