I know how to find finite differences such as first or second differences. But what if the co-ordinates gives are in random order.
In the case on top, the x values are increasing consistantly but what if the were in random order such as x 1 3 3 -3 4 -9 2 1
In the case on top, the x values are increasing consistantly but what if the were in random order such as x y 1 3 3 -3 4 -9 2 1
Arrange them in order first, then try
But sometimes they are really random and have no pattern at all. Here in my example its evident that the x increases by one but what I was given totally random values
So what im trying to say is that the x values do not increse by the same amount
