Let x be the number in the middle.
Then two other numbers are (x-2) and (x+2).
The sum of the three numbers is
(x-2) + x + (x+2) = 1368,
or
3x = 1368
x = 1368/3 = 456.
ANSWER. The numbers are 454, 456 and 458.
Solved.
----------------
In the future, if you have such problem with different sum, simply divide
the sum by 3: it will give you the middle number.
This simple trick works ALWAYS, saving your time.
