1+1=2 1+2=3 2+3=5

as in add the previous two numbers together…

1, 1, 2, 3, 5, 8,

fibonocchi numbers I think, that’s how it starts anyway, it goes away from this…

Edit

Fibonacci

1,2,3,5, 8, 11, 17, 28, 45, 73, 118, 191, 309

The 11 and 17 is wrong, but after that it still continues adding the prervious two numbers…

and just to be fair because the later numbers in the sequence add up but aren’t true Fibonacci numbers the person who came up with the sequence made the mistake and not your typing…

1,1,2,3,5,8,11,17,28,45,73,118,191,309

or

1 1 2 3 5 8 11 17 28 45 73 118 191 309

or

1-1-2-3-5-8-11-17-28-45-73-118-191-309

Created by the ancient world, re-invented by an Italian mathematician as a way to describe the reproduction habits of bees.

In modern times, it is occasionally used as an art motif (in paintings and tile work), and is mentioned in the DaVinci Code (the movie, as I’ve not read the book.)

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144…

(i think you made a typo in the numbers you typed in.)

you add the first and second to get the third term

the second and third to get the fourth term

the third and fourth to get the fifth term and so on.

it’s a famous mathematical progression that can be found in nature, architecture, music, and much more.

if you divide the n+1 term by the n term, (ie 3/2; 5/3; 13/8 etc) the quotients rapidly approach the number phi, which is usually written as 1.618

😉

Actually, I thought it was the sequence of 1+1=2, 2+3=5, 3+5=8, but it isn’t because the next numbers “5+8” should equal “13” and you typed “11,” so I’m sorry, but I don’t actually know.
