Related to geometric progression.

Find the values of x and y of the geometric progression x, - 4/3, 8/9, y.

I don't want the answer to this question, rather just whether it is actually possible. So far I have found m = 10 and r = 2 (or alternatively m = 0 and r = -1/2) which gives the consecutive terms...

Hi there, would love for any help on this topic. Thanks in advance!
