If the sum of first p terms of an A.P. is equal to the sum of the first q terms, then find the sum of the first (p + q) terms.

If the sum of first p terms of an A.P is equal to the sum of the first q terms, then show that the sum of its first (p+q) terms is zero. (p ne q) .

If the sum of first p terms of an A.P is equal to the sum of the first q terms , then find the first (p+q) terms .

If the sum of first p terms of an A.P is equal to the sum of first q terms, then show that the sum of its first (p+q) terms is zero . (p ne q) .

If the sum of first 20 terms of an A.P. is same as the sum of its first 28 terms, find the sum of its 48 terms.

The sum of first p- terms terms of an A.P. is q and the sum of first q terms is p, find the sum of first (p + q)

The sum of first P terms of an A.P. is equal to the sum of its first Q terms. Show that the sum of its first (P+Q) terms is zero.

The sum of the first p terms of an A.P. is q and the sum of the first q terms of the same A.P. is p. Find the sum of the first (p+q) terms of the A.P.

The sum of first p- terms terms of an A.P.is q and the sum of first q terms is p,find the sum of first (p+q)

The sum of first P terms of an A.P. is equal to that of the first Q terms. Prove that the sum of first (P+Q) terms is zero.
