Re: Bafflers?

I forgot the problem and the solution, solved it again in a different way and now cannot remember that!

Re: Bafflers?

That's bad!
I'll take a note of the solution, very good recurrence.

Yes, write everything down, now! Do not wait for later is a good rule.

Hi;

Thanks for looking at the problem. I am writing down the solution also.

Hi bobbym

Can you help with getting the solution. Even these are hard for me.

On my desktop our laptop I would've took time to write all that.I just cannot force myself to LaTeX on my phone.

Re: Bafflers?

Because it's late.

Back to the problem.I just done the recursion, stick in 10 and I'm done?

Re: Bafflers?

The other would be to find all the elements up to the tenth one from the formula.But the other one is the fun way.

Fun? Maybe... What if there were 10^12 iterations?
