quick google search showed there is a “cheat” to solve any number sequence using “interpolating polynomial” which I still don’t know what it is, but by entering the sequence into an online calculator it gave me the overly complicated but nevertheless correct formula:
now all I had to do was replace “x” with 8 and 9 for 8th and 9th number in the sequence (all on my ios calculator app, by hand 😂)
and after all that work I still see @ssjsasha beat me to it by 3 hrs haha
:D i appreciate the attempt but I can tell you it won't be that exactly.
If you wanna change your answers a bit so they're not exactly the same as @ssjsasha's it would qualify you for the contest.
