Re: Sequences!

Here is another sequence:

1,2,2,2,2,4,4,4,8,8,8,8,8,16,16,16,16,32,32,32...

Find as much about this sequence as you can.

Hi;

I know that, but it is still one possible answer.

Re: Sequences!

I know that too. I got my answer from a little trick. Now the chance that it coincided with what you wanted was about a billion to one...

Thanks for the extra terms.

Re: Sequences!
