Suppose you begin with one pair of newborn rabbits. At the end of the third month, and at the end of every month thereafter, they give birth to two pairs of rabbits.
Each pair of offspring reproduces according to the same rule. Assume that none of the rabbits dic. Let fn be the number of pairs of rabbits at the end of month n,
just after the new pairs have been born. We have f₁ = 1, f2 = 1, and f3 = 3. Which of the following is a recurrence relation for fn?
Select one:
O A. fn
fn_1 + fn_3
O B. fn
fn-1 +2fn_2
O C. fn
fn-1 +2fn 3
O D. fn = fn-1 + fn_2 + fn_3
