    N was a quadratic with no constant at the end o.o
    it was something like
    7N^2 + 15N = 2512
    N(7+15N) = 2512
    N= 2512
    N= 167 o_o


    That sequence was an arithmetic progression...right? please tell me yes.


    I hope so:confused:

    I was doing Soloman papers as mock exams, I found the real thing so much easier.

    The only question that stumped me was the Sigma notations of 2N and N
    I couldn't get to a correct integer solution from the quadratic equation

    I have created a new thread and posted all the answers. The reason why I didn't post them in here was because all the OCR MEI people might get confused and pile in here and I wanted a clear thread title.

    i got N=16
    area between curves= 16/3
    coefficient of w^6= 35/256 or something around that but i think that might be wrong
    Yep, I got the exact same as this. So did a lot of people who I talked to after the exam. Thought the rest of exam was pretty easy
