siquidem m est integer positivus maior quam jx-j-1, erit 
[m, fx —|— 1) = ([x, [x) —(— x (¡x —j— 1, jx) —(— xx[\l-\- 2, jx) -f- x 3 ([x-f- 3, jx) -j- etc.

Hinc patet, si pro aliquo valore determinato ipsius [x quaevis functio (m, ¡x) 
integra sit, existente m integro positivo, etiam quamvis functionem (m,jx —j— 1) 
integram evadere debere. Quare quum suppositio illa pro ¡x = 1 locum habeat, 
eadem etiam pro ¡x = 2 valebit, atque hinc etiam pro jx = 3 etc., i. e. genera

Duas iam progressiones considerabimus, quae ambae ad scopum nostrum 
ducere possunt. Progressio prima haec est
