# Find N Distinct Evenly Spaced Perfect Squares [duplicate]

I understand that it's possible to find 3 distinct evenly spaced square numbers is possible by finding a rational solution to the equation:
$$x^2+y^2=2r^2$$
Where $$r$$ is a rational number.
But I have no idea how to apply this to finding a larger amount of evenly spaced perfect squares, or if it is even possible.

• Yes, it does, thank you very much. – H4H Dec 2 '20 at 3:04
