If the sum of n terms of an A.P. is `(pn+qn^(2)),` where p and q are constants, find the common difference.

If the sum of n terms of an A.P.is nP+(1)/(2)n(n-1)Q, where P and Q are constants,find the common difference.

If the sum of n terms of an AP is Pn+Qn^(2) where P,Q are constants,then its common differc

If the sum of the first n terms of an A.P. is pn+ qn^(2) then its common difference is

The sum of n terms of an A.P. is (n^(2)+5n). Its common difference is :

If the sum of n terms of an A.P is (4n^(2)-3n)/(4) then ,n^(th) term of the A.P

If the sum of first p terms of an AP is ap^(2)+bp find the common difference

Show that the sequence defined by a_(n) = m + (2n - 1) d, where m and d are constants , is an A.P. Find its common difference .

If p^(th) term of an AP is q, and its q^(th) term is p, then what is the common difference?
