Abstract:
The equation commonly known as Sury's identity is a deceptively simple
summation formula that connects the Lucas numbers, Fibonacci numbers,
and powers of two. Many authors have given extensions and generalizations
over the years; in this paper, we take a different approach that allows
us to produce a good number of new summation formulas, all from elementary
(but non-trivial) methods.
