Hey HF! 😁

Saw this numberphile video and thought it was intreseting, so I just wanted to share it with you guys. ✌

(Try to figure out the sequence before you watch the video, just to see if you can get it. 🎉)

Sequence:
1
11
21
1211
111221
312211
What's next? 🤫




That's it, nothing too special.. just thought it was interesting. 😁

Wait lemme do some math.
Are you doing something like a couple 1s go together and it gets shifted up 1?
STILL WORKING ON THIS GIMME A SEC

RULES: concatenate any 1's together, not the other numbers
concatenating only happens in the first step, not the later steps
After concatenating, put a 1 on the right side, and a 1 always goes on the outside
Also, after a new number is introduced ex: 2 or 3 for the first time, a 1 has to go in front of it
maybe a 1 always goes on the left side of every number?
If you concatenate the 1 goes on the right side, otherwise it goes on left side

1
1<-1
11
(11)<-1
21
First rule comes here:
121
121<-1
1211
Now you start again. You have to concatenate first though.
1211
12(11)
122
There are two 2's therefore the two 1s before the two 2s
11122
11122<-1
111221
First you concatenate
111221
(111)221

I SOLVED IT CORRECTLY ISH AFTER SO MANY TRIES

1
11
11

(11)
21
21

21
1211
1211

1211
1112(11)
111221
111221
this is where it gets weird
NEW RULE if two numbers(over 1)are together that are the same ie 22 they stay together without adding new numbers
111221
(111)221
312211
312211

Balls to the walls time
312211
3122(11)
13112221
13112221

Okay I get the first three moves
1
1<-1
11
(11)<-1
21
So maybe a rule is that a one is added on the left side of a two?
121
121<-1
1211
Then you could add another 1 on the end and smash the 1's together, getting 2 1's on the left
1211
12(11)
122
11122
11122<-1
111221
and I get that
111_ 221
(111)12211

Think simpler & it helps to read each number aloud. :]

"Think simpler"

Well that helps a lot.

I think I figured something out though. Every number other than 1 has to be followed by a 1, unless there is a number in front of it. Also, while 1s can carry over, they do not always

Glad I could be much of help 😏
haha yep, seems that you got it. Just watch the video to check it. 🤗
(*cough* Now you should try my challenge #6 cough 😉)
