%N A114829 Each term is previous term plus floor of geometric mean of all previous 
               terms.
%C A114829 What is this sequence, asymptotically? a(n) is prime for n = 2, 3, 7, 
               10, 11, 14, 18, 24, ... are there an infinite number of prime values?

%F A114829 a(1) = 1, a(n+1) = a(n) + floor(GeometricMean[a(1),a(2),...,a(n)]). a(n+1) 
               = a(n) + [((a(1)*a(2)*,...,*a(n))^(1/n)].
%e A114829 a(2) = 1 + floor(1^(1/1)) = 1 + 1 = 2.
%e A114829 a(3) = 2 + floor[(1*2)^(1/2)] = 2 + floor[sqrt(2)] = 2 + 1 = 3.
%e A114829 a(4) = 3 + floor[(1*2*3)^(1/3)] = 3 + floor[CubeRoot(6)] = 3 + 1 = 4.
%e A114829 a(5) = 4 + floor[(1*2*3*4)^(1/4)] = 4 + floor[4thRoot(24)] = 4 + 2 =
