The study of prime number in any number sequence is crucial part. In recent year Panda and Behera introduced a new number sequence that is solutions of Diophantine equation 1 + 2 + 3 + … + (n – 1) = (n + 1) + (n + 2) + … + (n + r), where n and r are positive integers. The pairs (n, r) constitute a solution of above equation then n is called balancing number and r is the corresponding balancer. In this paper, we prove a main result that there is no prime number in the sequence of balancing numbers.
