I got this one, but I worked it out differently. Great teaser!

Great job! I usually get these number sequences, but you got me

Not too good at math, but great teaser

I never get these. Nice job!!

I got this as (n^3)-n, which, I now see, is just a mathematical identity of (n-1)*n*(n+1), starting the series at n=2. Very good teaser.

or n(n+1)(n+2) starting the sequence at 1?
