Subject: [seqfan] estimating growth of a sequence
Dear Sequence Fans, This is a problem that I encounter all the time. I have
120 terms of a sequence, and I want a good guess for the asymptotic rate of
My current problem is A156043. I created a b-file of 120 terms.
Very crudely it seems that
a(n) is approaching 4^n / ( 6 n ln n).
But I don't have much confidence in that.
Is there a package in Maple or some other language that will do this sort of
Statisticians must need this.
