%N A178359 Rounded up arithmetic mean of digits of n appended to n, cf. A004427.
%C A178359 A010879(a(n)) = A004427(a(n)) = A004427(n);
%C A178359 a(A178358(n)) = A178358(a(n));
%C A178359 subsequence of A178403.

%F A178359 a(n) = A008592(n) + A004427(n).
%e A178359 For n=8379: A004427(n) = ceiling((8+3+7+9)/4) = 7; so a(8379) = 10*8379 + 7 = 83797.
