In that same article, you have some iterations

  8 / 41 = 0.1951219
  (8 + 41 = 49) / 8 = 6.125
  (49 + 8 = 57) / 49 = 1.16326531
  (57 + 49 = 106) / 57 = 1.85964912
  (106 + 57 = 163) / 106 = 1.53773585

That second line is screwed up, which also screws up the subsequent lines. It should look like

  (41 + 8 = 49) / 41 = 1.19512195

which then means the line after that should be

  (49 + 41 = 90) / 49 = 1.83673469

and so on
