what happens when the 3rd difference is zero? Is the sequence 13, 23,31,41,49,67,77 a quadratic or cubic or something else. I appreciate your help with this.
3 rd differences are zero means second differences are same. That means it is Quadratic.
@@c4maths thank you.
The problem with the second difference is that they are not constant, we have -2,2,-2,2...which is not the same value.
Yes. It is not a quadratic sequence.
@@c4maths the question is "what is-it?" I have never encountered such a case. Any idea on your part?
