Cubic Sequences - Alternative Method

[@gemsx2045]

Thank you so much I have been looking everywhere for a video that would explain the alternative method for cubic sequences

[@sriyaniperera6674]

Thank you so much . Your explanations are as clear as Cristal

[@kaututandila7314]

Thanks a lot dude, it helps me a lot.

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

[@sakthishridevis998]

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]

you would still divide by 6

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

[@sissi9100]

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

[@omaralfrouh3994]

can you solve the one with steps:
-3,13,57,147,301.......

This may be a late reply but i suggest this video : ua-cam.com/video/ckH7MaF_a8Y/v-deo.html. Its a bit long but help alot. The answer to that question is 3n^3 -4n^2 +7n - 9
