suppose you subtract the second - first = 1
third - second = 5
fourth - third = 9
fifth - fourth = 13
to get the "first differences" of 1,5,9,13
now suppose we repeat the same procedure
5-1 = 4
9-5 = 4
13-9 = 4
notice we now have "constant differences" but we had to do it twice.
general concept:
if the first differences are constant, then the data came from a first degree relation
if the second differences are constant, then the data came from a second degree, or quadratic relation
if the third ....
