Let A = { a 1 , a 2 ,…} ( a 1 a 2 A ( n ) be the number of elements of A not exceeding n , and denote by R 2 ( n ) the number of solutions of a i + a j = n, i ≤ j . In 1986, Erdős, Sarkozy and Sos proved that if ( n − A ( n ))/log n → ∞( n → ∞), then . In this paper, we generalise this theorem and give its quantitative form. For example, one of our conclusions implies that if limsup( n − A ( n ))/log n = ∞, then for infinitely many positive integers N .
