EXAMPLE

879 is a term as the arithmetic mean of the digits is (8+7+9)/3 = 8.

MAPLE

Q:= proc(n, t) option remember; local j, R;

      if t > 9*n or t <= 0 then return [] fi;

      R:= NULL;

      for j from 0 to min(t, 9) do

        R:= R, op(map(s -> 10*s+j, procname(n-1, t-j)))

      od;

      [R]

end proc;

for i from 0 to 9 do Q(1, i):= [i] od:

seq(op(sort(Q(d, 8*d))), d=1..4); # Robert Israel, Dec 07 2020
