When writing out the values of a sequence in order to get a foothold on a problem, should you write them horizontally in a line or vertically in a table?
Vertically in a table.
When looking at a recursively defined sequence, what should you consider?
How repetitions might occur.
If
\[F(2k) = F(k)\]
and
\[F(2k + 1) = F(k)\]
at a minimum, where will $k$ be repeated?
At $2k$ and $2k + 1$.
After you’ve written out the values of a sequence in a table, what should you look for and why?
Patterns; there has to be some sort of simplifying relationship or they wouldn’t ask the question.
