Determine whether the series [PLAIN]http://img265.imageshack.us/img265/69/44751948.jpg [Broken] converges or diverges and find its sum S if it does converge.

2. Relevant equations

3. The attempt at a solution

my textbook has lots of weird examples but none of them help me understand how to solve this one..

if i plug in 1 then 2 then 3.... i get

ln(1.5) + ln(1) + ln (7/8) +...+ln((2n+1)/(3n-1))

so a = ln(1.5)

r = ?

then i use the formula: a / (a-r)

right? now how do i find r?
