Let k ≥ 1 and t ≥ 0 be two integers and let d = k2 + k be a positive non-square integer. In this paper, we consider the integer solutions of Pell equation x2 - dy2 = 2t. Further we derive a recurrence relation on the solutions of this equation.<\/p>\r\n","references":"[1] Arya S.P. On the Brahmagupta-Bhaskara Equation. Math. Ed. 8(1)(1991), 23-27.[2] Baltus C.
