<PRE><B>Question 1029205</B>
Given that x / x-1 is the first term of a geometric progression and x^2 / x^2-1 is the second term of the progression, in terms of x determine the common ratio and the third term of the progression.
-----
r = [x^2/(x^2-1)]/[x/(x-1)]
----------
r = [x^2/(x^2-1)]*[(x-1)/x]
----------
r = x/(x+1)
------------------------
a(3) = [x/(x-1)]*[x/(x+1)]^2
-----
etc.
