Two large numbers of the Fibonacci sequence are F75 = 2,111,485,077,978,050 and F76 = 3,416,454,622,906,707. If these two numbers are added together, what number results?
a. F151
b. F78 - 1
c. F74
d. F77

Answer 1

NOTE:  Fibonacci numbers is a sequence, where $F_n=F_{n-2}+F_{n-1}$  for n>1.  

Therefore $F_{75} + F_{76} = F_{77} \ \ \hbox{Answer d)}$
