As soroban pointed out you can start with any constant as the initial values for the fibonacci sequence. For example:
c,c,-> 2c,3c,5c,8c,13c,21c... this sequence is only the fibonacci number times by c, so when you take the ratio (c*F[n+1]) / (c*F[n]) the c's will cancel and you will get F[n+1] / F[n] which
converges t... | {"url":"http://www.mathisfunforum.com/viewtopic.php?pid=114192","timestamp":"2014-04-21T07:14:18Z","content_type":null,"content_length":"23466","record_id":"<urn:uuid:9fca01b2-6de4-4315-a433-f7a2b6da4f17>","cc-path":"CC-MAIN-2014-15/segments/1397609539665.16/warc/CC-MAIN-20140416005219-00219-ip-10-147-4-33.ec2.internal... |

Small data
Big data is getting a lot of buzz lately, but small data is interesting too. In some ways it’s more interesting. Because of limit theorems, a lot of things become dull in the large that are more
interesting in the small.
