I have the following series 3/2, 4/3, 5/4, 6/5....
the nth term could be expressed as n+2/n+1.
I cant seem to work out how to get the limit of this function as most of the books describe the sum to infinity as a/1 -r.
With a = 3/2 and being the first term, I am confused as to what r should equal. As this sequence does not seem to have a common ratio. I thought that r would be the common ratio.
Maybe I am going down the wrong line of thinking so please clarify how to find the limit and the r variable in the equation.
Many Thanks
