Use the method of common differences to output a vector containing the initial values and the nth order difference.

ex [ 1 4 9 16 25 36 ] has 1st differences [ 3 5 7 9 11 ] and second differences [2 2 2 2] . Therefore output [1 3 2] which is the 1st element of the above three vectors.

The use of this is that the sequence can be continued by using these differences.
