Yes, a properly timed delivery of a few fun facts about the famed Fibonacci sequence just might leave your friends clamoring for more—because it really is that cool. So, without further ado, let’s continue our exploration of sequences that we began a few articles ago by jumping right in and talking about Fibonacci’s famous sequence.
