Why did the vector cross the road?
It wanted to be normal.

Re: What's going on? Crazy sequence

Are the terms in each sequence of this series bounded?  Prove it.

Re: What's going on? Crazy sequence

I can't figure out any of this.  Can you give me a hint as to how this works?

You were not alone. I was at sixes and sevens as well. I had to google the Web for the solution to the conundrum myself, hehe. lol

Re: What's going on? Crazy sequence

Like Ricky said, say the numbers out loud...

one
one one
two ones
one two, one one...

As for the continuations posted, it looks like they're all right.
