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 - ,

    generally the 1st term is called a, but if that's what c is, then

    S = c/(1-r) so

    4/(1-r) = 16
    1-r = 1/4
    r = 3/4

    THnak you!
