Answer:
One of X , X+2 , and X+4 must be divisible by 3. Because of this, all three can be prime only if one of them is 3.
X=3 gives 3, 5, 7 which works.
X=1 gives 1, 3, 5 does not work because 1 is not considered a prime.
X=−1 gives the even more ridiculous -1, 1, 3.
So, 3, 5, 7 is the only such triplet, although there are prime triplets of the form X , X+2 , X+6 or X , X+4 , X+6 .
