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
@@happynoobyt1196 OMG bro, literally finished my secondary education, A Levels and about to enter university, such a long time since then. Thank you anyways.
Thank you so much I have been looking everywhere for a video that would explain the alternative method for cubic sequences
Helped me a lot . Thanks !
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
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?
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
I got un=n^3+2n^2+3n-5
can you solve the one with steps:
-3,13,57,147,301.......
