More Proof by induction(the rearranging bit) watch

    (Original post by RDKGames)
    Keep in mind that would give you the U_{k+1}. For U_k you'd need to map k \mapsto (k-1) on the right side. This would give you the exact same thing as mine would and proof would hold.

    The proof for showing the results for  U_k or  U_{k+1} are equivalent, they're exactly the same. With induction all you need to show is that if the result is true for  U_k then using logical arguments it implies that the result is also true for  U_{k+1} .
    awesome thanks both
