Dear seqfans,
Just submitted
%S A114705
6,14,48,98,372,868,2784,7236,27744,64708,215040,541156,1947840,5168548,23046144,43129476,155189760,444228512,1398675600,3623742864
%N A114705 Sum of divisors of 2^n + 3^n.
%C A114705 All terms are even? Cf. A000203 sigma(n) =
sum of divisors of n.
My questions are:
All terms are even?
Equation 2^n + 3^n = x^2 has no solution (with integer
x and n)?
Thanks, zak
