Is there a way to work what you divide the difference by to get the coefficient for sequences of higher degree

@jonathanlee1692 3 года назад

Hi , i wonder why this sequence couldn't be solved with this method As shown: -1,1,-5,-25,-65

@sissi9100 Год назад

I got un=n^3+2n^2+3n-5

@sakthishridevis998 3 года назад

Just a doubt... what if the third difference of the sequence is not six or its multiple? ie: what if its 3 or 10 etc?

@xdgaming952 3 года назад

you would still divide by 6

@omaralfrouh3994 4 года назад

This may be a late reply but i suggest this video : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ckH7MaF_a8Y.html. Its a bit long but help alot. The answer to that question is 3n^3 -4n^2 +7n - 9
