Is "between...and..." inclusive or exclusive on GRE?

Is “between…and…” inclusive or exclusive on GRE? Thanks!

I have heard Greg mention multiple times during lectures, that GRE tends to avoid any discrepancy. So if they want you to consider the extreme values, they will mention the term ‘inclusive’. i.e.

x is an integer between 2 and 4, means x = 3.
x in an integer from 2 to 4, inclusive; x={2,3,4}
