Determine the integer(s) n for which [n²/3] is a prime.
Note: [x] is the greatest integer ≤ x (floor function).
(In reply to I got it, i got it
However, since n must be an integer( whether positive or negative) n= -3, for the case n=3a, and n=-4 corresponding to the case n= 3a+2 are also valid.
Thus, n= +/-3 and n= +/-4 gives all possible solutions to the given problem.
