    Let us assume the first number = x

    Then the second number = 5x - 2

    The third number = x + 4

    The total number that needs to be divided into three parts is 219

    Then we can write the equation as

    x + 5x - 2 + x + 4 = 219

    7x + 2 = 219

    7x = 219 - 2

    7x = 217

    x = 217/7

    = 31

    Then

    First number = 31

    Second number = 5x - 2

    = (5 * 31) - 2

    = 155 - 2

    = 153

    Third number = x + 4

    = 31 + 4

    = 35

    So the three numbers are 31, 153 and 35.
