Answer 1

@agent0smith

Answer 2

let's assume that the missing term is "x"
then if the common ration is "r"
then
250*r = x
also
x*r = 50
r = 50/x
substitute it in the first one
250*(50/x) = x
x^2 = 1250
= nearly .. 111.8

got it :) ?

Answer 3

srry the last part should be corrected as this
x^2 = 12500
x = 111.8

Answer 4

why does it go up and back down? I'm confused by this question
