my book says that if sum of p terms of an ARTHMETRIC PROGRESSION is q and sum of q terms is p , then sum of p+q terms will be (p+q) , but i am getting it as +(p+q),
can someone verify it ?????

Can you post your work?
Just messed around with it for a couple minutes and I got p+q+p*q*d where d is the common difference.
