Stephen's late post

ok so this week was long and i forgot everything bout school soo this is late. these are formulas for arithmetic and geometric.

Arithmetic:
tn-t'+(n-1)d
n=term #
t'=first term
d=what you add
tn=term#_in sequence


Geometric
tn=t'∙r^(n-1)
r= what you multiply by

Again i dont really know much so idk whatr i needa know so i guess i just needa be refreshed a bit on a few stuff.
