a. x%5E2-1 x is natural numbers
b.x%5Bn%5D=x%5Bn-1%5D+%2B+%282n%2B1%29 where x%5B0%5D=10 1st term, n is natural numbers
c x%5Bn%5D=x%5Bn-1%5D+%2B++%284n%2B2%29 where x%5B0%5D=2 1st term, n is natural numbers
d.x%5E3 where x is the natural numbers

(B) n%5E2+%2B+9
{C) 2n%5E2
(D) n%5E3
These are pretty hard- don't feel bad- the more
you plug along with these the better you get
