A069887 Number of terms in the simple continued fraction expansion for (1+1/n)^n. 5

%S 1,2,5,7,7,10,14,16,24,16,20,29,39,40,42,39,46,42,44,57,59,55,66,55,

%T 57,70,68,81,86,81,91,109,106,108,119,117,123,118,124,118,120,133,142,

%N Number of terms in the simple continued fraction expansion for (1+1/n)^n.

%C Limit_{n -> infinity} (1+1/n)^n = e.

%C For any natural number N, limit_{n->infinity} (log(N)^(1/n) + 1/n)^n = e*log(N). - _Alexander R. Povolotsky_, Dec 06 2007

%F Asymptotically it seems that a(n) ~ C*n*log(n) where C = 0.84... is close to the constant described in A055573.

%e The simple continued fraction for (1+1/10)^10 is [2, 1, 1, 2, 5, 1, 128, 1, 2, 12, 5, 3, 46, 1, 11, 7] which contains 16 elements, hence a(10) = 16.
