    so what i'm thinking is that you let

    x_n+3 + x_n+2<=x_n+2 + x_n+1 <= x_2 + x_1

    then show that the first term can eventually go to the last term

    squeezing the term into the middle

    but the problem with this is i dont see where the 1/3 comes from

    any ideas?

    The third term is AM of its previous two terms.
