%N Numbers of the form (3^a+5^b)/2 ; a,b >= 0 (with repetition).
%C Elements of the table A193770 (motivated by the less fundamental A081458), sorted by increasing size.
%C The value 14 = (3^1+5^2)/2 = (3^3+5^0)/2, therefore it occurs twice.
%o (PARI) select( t->t<3000, vecsort(concat(Vec( matrix(9,6,x,y,(3^(x-1)+5^(y-1))/2 )))))
%Y Cf. A193770 (the table), A081458 (the subtable obtained for even a,b).
