    Cant the ans be in a better form like 2^n(n!)^2/(2n+1)!
    This was identical to a reduction given in step III 2015 q 1.

    Yh it was fthe first part of a 6 part question. Very simple indeed. I emant your answer can be simplified into my nicer looking version.

    Maybe it is late.
    Ive just simplified your answer.
    Yours is 2^n+1(n!)(n+1)!/(2n+2)!
    Pull 2(n+1) from top and bottom and you get my answer.

    Did you pull 2 out of the factorial at the bottom?


    I hope nobody from Cambridge is looking at this...

    Not really lol
    Okay so your answer is
    2^n+1(n!)(n+1)!/(2n+2)!
    The top can be writte as 2x2^nxn!xn+1xn!=2(n+1)2^n(n!)^2 right
    Bottom 2n+2!=2n+2(2n+1)!
    Now the 2n+2 cancel to give my answer. Where am i going horribly wrong ?? Lol

    I hope there is no typo in the answer ...
    do your solution tomorrow and when I post my solutions we discuss it again.
    (i do not think you can do any meaningful simplification to that but I am the King of Blunder)
