Primary Product (Posted on 2003-06-02) Difficulty: 2 of 5
Do there exist three integers in Arithmetic Progression whose product is prime ? If Yes, then what are the three integers and if No, then why ?

[Note: The numbers: x1, x2, x3, x4, x5, x6,........ are said to be in Arithmetic Progression if (x2 - x1) = (x3 - x2) = (x4 - x3) = (x5 - x4) = ........ and so on].

-1 - (-3) = 2
1 - (-1) = 2 also,
so it's an arithmetic progression; the numbers are equally spaced along the number line.
