This is caused by an invalid arithmetic or mathematical operation, like dividing by zero. For this challenge, I have added yet another end point to find the ratio for a given index and its predecessor. For instance, if the index requested is three, we would retrieve the third number in the Fibonacci sequence, which is two. We would also retrieve the second index in the sequence, which is one, two divided by one is the ratio between the index requested and its predecessor. And the result which is two, is what the end point will return. Why do we care about generating the ratio beyond needing some way to do this challenge and trigger an arithmetic exception? Well the ratio between two consecutive numbers in the Fibonacci…
