What does the recursive relationships mean and why are they so important to know?
A recursive relationship means a term of a given sequence can be computed in terms of one or more of the previous members of the sequence.
Something like
$s_k = f(s_{k-1},~s_{k-2},\dots,~s_1)$
They are useful to know for actually calculating values and sometimes the recursion itself can reveal underlying principles of the sequence.
