Can someone please show me step by step how to solve this, I've been stuck.
Find the common ration r of the geometric series an that satisfies the following conditions: c=4, S=16
I would reallyy appreciate it if someone could help me

math 
Steve,
generally the 1st term is called a, but if that's what c is, then
S = c/(1r) so
4/(1r) = 16
1r = 1/4
r = 3/4 
math 
mysterychicken,
THnak you!
