(a) State the definition of a (k + 1)-term linear recurrence relation.
(b) Let (F(n))n>o be a sequence that satisfies the recurrence relation
F(n) — 4F(n — 1) — ЗF(n — 2) for
n > 2
with initial conditions F(0) = 2 and F(1) = 4. Find the solution to the recurrence
relation – a closed form expression for F(n).
(c) If (F(n))n>o is a sequence, write down the generating function for (F(n))n>0-
(d) Suppose that (F(n))n>0 is a sequence that satisfies the recurrence relation
F(n) = 3F(n – 1) + 10F(n – 2)
for n> 2
and with initial conditions F(0) = -1 and F(1) = 9, use the technique of generating
functions to find a closed form for F(n) for n > 0.
