more interesting, that the thread starter can solve:

What's the largest digit in the 100th term of the sequence?

Sorry, I'm not the threead-starter either.

You need not go down to 100 the biggest possible digit arises much earlier

But can you verify that it remains in the 100th term?

trivial, any digit wich occures stays there since it is counted the next time.

That doesn't prove it remains the biggest digit.

In the usual decimal system, which consists of ten digits, there is only one of these that is biggest and this is, of course, the digit nine (9).

True, but that was not what was asked of him 🙂

It is trivial to show that 3 is the highest digit which can be obtained.

It is even more trivial that a digit which occures once occures every line after (which was the question I replied to)
