%N Numbers n for which the first difference sequence of A054040 decreases.
%C Same as asking when the second difference of A054040 is 1.
%e A054040(27)A054040(26) = 13 while A054040(26)A054040(25) = 14, therefore the first entry is 27.
%t k = s = a = b = c = 0; Do[m = n; While[s < n, k++; s = N[s + 1/Sqrt[k], 50]]; a = b; b = c; c = k; If[2b  a > c, Print[n]], {n, 1, 4400}]
