Sažetak
We study integer sequences defined by the recurrence \(U_{n+2}=p + U_{n}\) and the initial values \(U_{0}=a,U_{1}=1\) , for n ≥ 0. We find families of identities of these sequences, some of which Sury’s identities are a special case. We prove these identities by using a combinatorial interpretation by means of tiling. In particular, we present a tiling involution of the alternating sign dual of the first Sury’s identity.
