The first such triple is 8 = \(2^2+2^2\),9 = \(3^3+0^2\),10=\(3^2+1^2\), which suggests we consider triples \(x^2-1,x^2,x^2+1\).Since \(x^2-2y^2=1\) has infinitely many positive solutions (x,y), we see that \(x^2-1=y^2+y^2,x^2=x^2+0^2\)and \(x^2+1\) satisfy the requiment and there are infinitely many such triples.
