%N A092978 (Product of first n even numbers)/(product of first k odd numbers) where 
               k is chosen to give the least integer.
%F A092978 For n even, a(n+1)=2*a(n); for n odd, a(n+1)=2(n+1)*a(n). For n even, 
               a(n)=[2^(3n/2)]*(n/2)!; for n odd, a(n)=[2^( (3n-1)/2)]*((n-1)/2)!.

%e A092978 a(5) = 256 = (2*4*6*8*10)/(1*3*5) as (2*4*6*8*10)/(1*3*5*7) is not an 
               integer, here k = 3.
