Question

If 4,x-4 and 5-2x are the first 3 terms of an ab infinite G.P whose sum is finite , the value of this finite sum is .

Answer 1

the question doesn't make any sense!

Answer 2

its confusing
you can find the values of x which makes the series a GP by solving
(x -4) / s = (5 - 2x) / (x -4)

then find the sum of 3 terms

Answer 3

* (x -4)/ x

Answer 4

* (x-4)/4
