The arithmetic mean of 3 consecutive even integers would be the middle even integer.
That rules out both options B and C.

For option A to be the answer, the numbers need to be 22,24 & 26, but 22 is outside the range provided.

For option E to be the answer, the numbers need to be 30,32 & 34 but 34 is outside the range provided.

The answer is option D, and the 3 numbers are 26,28 & 30.
