Hint : 
$$F_{n} = F_{n-1}+F_{n-2}$$

ganeshie8 · Answer

$$F_{76} = F_{75}+F_{74}$$

anonymous · Answer

there is no f 75+ f 74 only subtraction

ganeshie8 · Answer

Right, you're asked to subtract the given two fibonacci numbers

ganeshie8 · Answer

Notice that you're given $F_{76}$ and $F_{75}$

subtract them, what do you get ?

directrix · Answer

F_74 + F_75 = F_76

directrix · Answer

F_74 = ?
