hey, i tried this way but it does not worked out for me or may be i do not grasp your solution. Please give me a detailed solution

sum up the series : 1/(1.3.5)+1/(3.5.7)+1/(5.7.9)+.......n terms.

I have no idea how to solve this inequality without using AM-GM inequality: for any positive integers p,q,x,y show that (pq+xy)(px+qy)>=4pqxy
