see my frnd
th last term will be = 1.5.9.- - - - -(4n-3) / 3.7.11. - - - - -(4n-1) using A.P.
so sequence becom 1/3 + 5/9 + - -- - - - - - - + 4n-3/4n-1
it sum up to 
= [2n(n+1)-3] / [2n(n+1)-1]

Fantastic work jishnu and this forum owes you for this. I had heard about this technique but I had never encountered it before. So, personally, thanks from me.
