Been reading about the Fibonacci sequence (the first few being 1, 1, 2, 3, 5, 8, 13, 21). 1+1=2, 2+1=3, 3+2=5 etc. Very interesting to read it all again, especially when you look at the sequence in nature and the golden ratio in pentagons etc. Then you can get into The Pyramids if you want.
It reminded me of this puzzle. What’s the next number in this sequence?
1 11 21 1211 111221
122111?
fibonacci is amazing. was amazing. whatever.
Nope.
12221111 ?
Don’t think so. It’s not the one I’m thinking of anyway. There might be more than one pattern here.
