Recursive Fibonacci

Question

I\'m having a hard time understanding why

#include 

using namespace std;

int fib(int x) {
    if (x == 1) {
        return 1;
    } else {
         


        

Answer 1

int fib(int n) {
    if (n == 1 || n == 2) {
        return 1;
    } else {
        return fib(n - 1) + fib(n - 2);
    }
}

in fibonacci sequence first 2 numbers always sequels to 1 then every time the value became 1 or 2 it must return 1
