Alright, so I just started my Calculus class, and we're doing Series and Sequences. We've been doing all these problems, and as I was doing them, I noticed that they all can be solved using the finite differences method. Why bother with sequences and series formulas when I can just use the finite differences table? Also, is this right: difference = a * degree factorial What I've been doing is making a list of values with x and y for simple values. Then, I calculate the a using the above formula. Then, I calculate b and c using other values. Is this the fastest and easiest method?
