Are there restrictions on what "n" can be? For instance, must n be (positive) integers themselves?
If yes, then it basically boils down to requiring the numerator to be even*. I'll leave the rest to you.
Much trickier if we are dealing with, say, n is real (then n could be, say, root(3)). Not to mention complex.
*Technically this is the one requirement, no matter what n can be. But it's much harder to find real/complex solutions.
If yes, then it basically boils down to requiring the numerator to be even*. I'll leave the rest to you.

The answer is n is greater or equal to √3, could you please explain to me why?

Pretty sure it's not. For instance, n can't be 2 > root(3).

How would you work out this question because I am quite confused
So I'm taking n to be real. A bit unconventional, but okay.
Actually, after a bit of thought, this problem contains unnecessary information.
A good starting point would be to let (n^2-1)/2 be some positive integer k, then rearrange terms.
A step even before this, is to simply play around - what n makes (n^2-1)/2 equal 1? How about equal 2? 3? Can you spot a pattern?
