    I'm moving on to this soon and while I can't really help with specifics, here's a summary of the main subtitles from the textbook.

    + A series of numbers following a set rule is called a sequence.
    + When you know a formula for the nth term (eg Un = 3n - 1) you can find any
    term
    + When you know the rule to get from one term to the next, you can use this
    information to produce a recurrence relationship (or recurrence formula)
    + A sequence that increases by a constant amount each time is called an
    arithmetic sequence
    + Arithmetic series are formed by adding together the terms of an arithmetic
    sequence U1 + U2 + U3...+ Un
    + You need to be able to find the sum of an arithmetic series
    + You can use SIGMA to signify 'the sum of'

    There's examples under each, but get that down and that's the material for c1.
