摘要：The original problem of quadruple was studied by the Since the Greek mathematician Diophantus of Alexandria 1/16 , 33/16 ,17/4 and 105/16 was the first set of quadruples found in 3^rd century (b.c) in which having any product of two terms increasing the set increased by 1 is a perfect square. Later Fermat obtained a set from integers as {1,3,8,120}, later davenport and baker both to generalize the fourth member of the set is, {1,3,8, d}.
Here in this work we will present a more generalized version of Diophantine quadruple, {p, q, r, s}, where any two of the product increased by n result will be a perfect square, i.e. pq+n=x^2 and, It is proved that the Diophantine quadruple , set of positive and negative integer number with the property that the product of any two of them plus n is a perfect square, than generalization of the result is obtained.
