two-way infinite sequences sequences related to :
- two-way infinite sequences (01): Many sequences can be extended backwards in a natural way. For example, the Fibonacci numbers (A000045) extend backards to give the two-way infinite sequence
- two-way infinite sequences (02): ..., -21, 13, -8, 5, -3, 2, -1, 1, 0, 1, 1, 2, 3, 5, 8, 13, 21, ..., satisfying F(n) = F(n-1) + F(n-2) = -(-1)^n F(-n) for all n. The backwards portion here is the same sequence but with signs, which is quite common, but in general a different sequence is obtained
- two-way infinite sequences (03): The following is a list of two-way infinite sequences. A pair in parentheses indicates that the backwards and forwards sequences are different. This entry is based on communications from Michael Somos
