    3x + 3 = 78

    3x = 75

    x = 25

    So the three numbers are 25, 26, and 27.

    Even consecutive numbers are 2 apart

    (2,4,6, example)

    so they are

    n, n+2, n+4

    their sum is 78

    n+n+2+n+4=78

    3n+6=78

    minus 6

    3n=72

    divide 3

    n=24

    smallest is 24
