    Here's the solutions. Includes other methods people had of doing certain questions, and the mistakes in my last ones have been corrected.

    Also, no one noticed, but I had a mistake in 2.c.iii. The answer is a>10.

    Question 4 is now included.

    NOTE: If any SEC Personnel feel this is a breach of copyright or something, say the word and they will be removed immediately. :)

    the sum to infinity question, i think it was part (iii) (at least i interpreted it as the sum to infinity, again i could be very, very wrong. i usually leave out sequences and series)

    As in when you're finding the sum of the thing you got in (ii) you got the a and r
    by putting in 1 and 2 for n in the expression for ak?
    Yeah that's fine! :)
