For the purposes of this problem, it does not matter exactly how the fi are defined,
only that they are recursively defined.
For integer n ≥ 1, let P(n) be the predicate that fn = 2n². Don't worry
about whether this predicate "makes sense"; we haven't defined the fi so you won't
be able to "make sense" of the P(n). It's not important for this problem.
Consider a proof by induction that Vn ≥ 1 : P(n).
Suppose that the first step of the inductive step is
fk+1 = k + fk−1
True or false: Based on the information given, we will need at least P(1), P(2) as base
cases for this proof.
