  1. let the integers be n, n+1, and n+2


    solve for n, notice it is a quadratic.

  2. Buy why wouldn't it be n, n+2, and N+4 because it is even ingergers,

  4. you are right, it should have been
    n, n+2 and n+4 so let's adjust bobpursley's equation to look like

    2n(n+4) - 28 = (n+2)^2

  5. lets start with the equation
    2n(n+4) - 28 = (n+2)^2
    using formula (a+b)^2=a^2+2ab+b^2

    Solving for n, we get n=4

    So the even consecutive numbers are 4,6,and 8.....
