Can you please compute asymptotic_a[n]-a[n] for a few n and post it here?

I do not understand that. What is a[n]-a[n]?

The first one is asymptotic_a[n], not just a[n].

Isn't that what the those fractions are in post #98 and 100?

It is not. Or at least it is not supposed to be. That should be a[n]/asymptotic_a[n].

Yes, you know what I mean. Okay, I will give the differences.

Hm, and what do you get for Floor[asymptotic_a[n]] for different n?

The floor function is a stepwise function, it is more difficult to work with.

Some analytical techniques have problems with anything other than a mathematicians dream like smooth functions. To use them you will have to split the recurrence into 4 of them.

Almost any of them also some M techniques too.

For instance take a try to find the series coefficient with M, with and without the floor function.

One will fail the other will not.
