Hi,
This topic has the following items:
1. AP/GP, in which there are results to recall;
2. Real-life problems involving AP/GP, where one has to
be able to determine whether to use AP or GP;
3. Binomial series (related to later topics Maclaurin's
Expansion and Small Angle Approximations), though easy at first
glance, may have parts that are challenging;
4. Recurrences, which is a difficult area to understand
with many students;
5. Summation of series, which also requires students to
recall results;
6. Method of differences, in which some parts are
problematic for many students; and
7. Mathematical induction involving conjectures often
stump students.
Have a look at my checklist of concepts and skills for a
detailed description of these items:

Thanks and happy learning!
Cheers,
