Answer 1

Answer:

B. F(52)

Step-by-step explanation:

In the Fibonacci sequence, each term is found by adding the previous two terms together.  This means that f(3) = f(2)+f(1), f(4) = f(3)+f(2), etc.

If we add f(50)+f(51), this would give us f(52).

Answer 2

$F(n)=F(n-1)+F(n-2)$ for $n\ \textgreater \ 1$

So $F(50)+F(51)=F(52)$
