On the Properties of Lucas-Balancing Numbers by Matrix Method

open access: closedSigmae, 2014
Balancing numbers n and balancers r are originally dened as the solution of the Diophantine equation 1 + 2 + ... + (n - 1) = (n + 1) + (n + 2) + ... + (n + r). If n is a balancing number, then 8n^2 +1 is a perfect square.
