E550  De seriebus, in quibus producta ex binis terminis contiguis datam constituunt progressionem
(On series in which the product of two consecutive terms make a given progression)
Summary:
Given a sequence (what Euler calls a "progression") A, B, C, D, E, F, etc. Euler
wants to find another sequence (that Euler calls a "series") a, b, c, d, e, f, etc.
such that ab=A, bc=B, cd=C, de=D, ef=E, fg=F, etc. He studies a variety of properties
of the second series.
According to the records, it was presented to the St. Petersburg Academy on July 4, 1771.
