A Fibonacci 3-subsequence is a subsequence of the type F n , F n+3 , F n+6 , . . . , where F k denotes the kth Fibonacci number. In this article, we investigate the reciprocal sums of the Fibonacci 3-subsequences and obtain several interesting families of identities involving the Fibonacci numbers. MSC: 11B39
