That's just ln|x-k|.

It is correct that it will have the digit 2, but what's more imortant is that it will always have a 1. Compare that to a double of a number from the sequence.
Hm, you have the correct answer for Q1?

Hm, I think we would be able to help you more if you tell us where this problem comes from.

Well, it's not primarily time that's making the matter hard. It's the concept of aging and also the concept of the speed of aging.

I have no idea... We should test that somehow.

Wonder when we will be the same age...

I do not know. Free will?
How do you know he is not?
#808 Re: Help Me ! » trigonometry » 2014-06-16 22:05:18
Well, I guess that, as I get older and you get younger, such things will start to happen.
#809 Re: Help Me ! » 64 pawns » 2014-06-16 22:04:01
I don't think that is true. The problem is quite hard.
#810 Re: Help Me ! » bases » 2014-06-16 22:02:16
That is correct.
Now, think about what a sum of two such number looks like and what twice a such number looks like.
Also, did you see post #25?

Hmm, okay then.

Hi cooljackiec
I found that these numbers satisfy Q2.
I have been able to prove that fact, unless I make a mistake somewhere. I will post my proof, if needed.
Also, the formula for Q1. is , I think, so all bases up to 32 have the property.

Hi Bob
I got the same thing you did, but I am blind. I thought 1 was the a) option.

Ok, we have N_b. Let's say N_b is in form of

Hm, unfortunately, just as I thought. This will be harder.

Oh, sorry, misread it. It seems like a mighty hard job counting them all.
