# I need a math wiz

because I suck at math.

But I found something that might be interesting. It is at least interesting to me. The Fibonacci sequence:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, ...

Starting with the second 1, if you take each set of four numbers (1, 2, 3, 5) sum the outer and the inner numbers and then divide the outer by the inner, you get 6/5. Or 1.2

Then you keep going, with each group of four (2, 3, 5, 8) and do the same. You keep coming closer to the square root of 5, -1. You come closest finally around the 11th set of numbers, then it starts veering off again. I'm just wondering if there is a pattern to it, or just coincidence.

- it is connected to the golden mean. It is the basis for all creation.

I don't know. Just trying to see if phi has something to do with the square root of 5,and why.

And the number 6/5 is important, for some reason.

There'll be someone around soon enough. And you know how some of these girls and boys love a challenge.

There is nothing to argue. So, don't hold your breath.

If you noticed that pattern, then you're much better at math than you give yourself credit for; don't know why you would claim that you suck at it.  It has to do with the fact that the ratio between consecutive numbers approaches phi = (1 + sqrt(5))/2

"In Ancient Greek, it represented [pʰ], an aspirated voiceless bilabial plosive (from which English ultimately inherits the spelling "ph" in words derived from Greek). In the system of Greek numerals, it has a value of 500 (φʹ) or 500,000 (͵φ). It may be that phi originated as the letter qoppa, and shifted as Ancient Greek /kʷʰ/ became Classical Greek /pʰ/. The Cyrillic letter Ef (Ф, ф) descends from Φ."
So interesting!
Right!?

Also, if you're curious, there's the journal called the Fibonacci Quarterly devoted to this stuff, and the issues are all available for free online.

The articles are aimed at a math/sci audience, but they're not all super technical and I'm sure you'll find many of them very accessible.  A lot of them discuss patterns like the one you found.

I want you to know I'm completely straight... but I think I might have a crush on you. Try not to let it bother you.

Zero is not part of it.
