Step-by-step explanation:
First, let us define what a set that is neither opened nor closed mean.
When we say a set of rational numbers is neither open nor closed. We are saying it isn't open because all the neighborhood of a rational number contains irrational numbers, and its complement isn't open either because all neighborhood of an irrational number contains rational numbers.
Now, a set that is neither open nor closed is a set that has an interval with one end open and one end closed, for example, [3, 4).
If we are to construct a sequence of open sets whose intersection is [3,4)
Then we say that:
Assume that G(n) = (-1/n, 1)
Then all G(n) contains [3,4).
