A140881 An asymptotic limit sequence of a non-algebraic number limit: Start term:a(1)=Log[4]/Log[3]; a(n) = a(n - 1)^(1 + 1/(n - 1)); Out_n=Floor[a(n)]. 0

COMMENTS

The asymptotic recursion is derived like this:

Mathematica gives:

Limit[Fibonacci[n]^(1/n), n -> Infinity] ==(1+Sqrt[5])/2

True

( Binet like result for a Fermat of Beta integer type)

The same limit is given by:

Limit[Fibonacci[n + 1]/Fibonacci[n], n -> Infinity]

Asymptotic sequence is in the Limit:

Fibonacci[n]^(1/n)=Fibonacci[n+1]/Fibomacci[n];

or a(n)=a(n-1)^(1+1/(n-1)).

This current sequence gives a low ratio limit

that approaches the transcendental limit of Log[4]/Log[3].

FORMULA

Start term:a(1)=Log[4]/Log[3]; a(n) = a(n - 1)^(1 + 1/(n - 1)); Out_n=Floor[a(n)].

MATHEMATICA

Clear[a] a[0] = 0; a[1] = Log[4]/Log[3]; a[n_] := a[n] = a[n - 1]^(1 + 1/(n - 1)) w = Table[Floor[a[n]], {n, 0, 50}]
