%N Smallest nontrivial positive power x such that the number of odd powers (i.e., odd base) not exceeding x exceeds by n the number of even powers not exceeding x.
%e a(3)=1601613 because there are 699 odd powers not larger than 1601613, and 696 even powers not larger than 1601613, and 699 - 696 = 3.
