Why isn't Fibonacci of 3 = 3 since (3-1) + (3-2) =2

Question

.

Answer 1

Maybe the confusion comes from some people starting the sequence at 0 and others starting it at 1?

Answer 2

Sonic Kondwani Mwape There is confusion because some people make a fibo sequence that the first number of it is 1, some of them make the first number 0. It is true that fibonacci starts from 0 and 0 is the first number of the sequence, not 1. That is why in a pseudo-code, the recursion of fibonacci function have a base if n is 0, return 0, else if n is 1 return 1, other than that you do recursive.
What made the confusion is also that when you do fibo (1) for example, it prints out 1 instead of 0, why is that? Because in programming (what I know), is that things starts from 0 like indexes of arrays, you can make your own code looks like if you input 1, it does fibo(input-1) and it will print out 0 instead of 1. I hope this is clear to understand.

LastSecond959 well said.

Answer 4

if the fibonacci sequence is defined to start at 0, then the sequence is 0,1,1,2,3,5,8,...then fib(0)=0, fib(1)=1, fib(2)=1, fib(3)=2, and fib(4)=3. it all depends on where you start the sequence, if started a 1, instead of 0, then fib(3)=3

Answer 5

How? bluesea

Answer 6

I was asking why Fibonacci of 3 isnt equal to 3

Answer 7

Sorry could you be a little bit more elaborate

Answer 8

Which is 3 right? But its supposed to be 2

Answer 9

Thank you

Answer 10

Because (3-1)+(3-2)= 3
