Also größer als 1. Als drittes Glied nehmen wir- t, so wird s3 = f, also wieder kleiner als 1. Damit eine spätere Teilsumme wieder größer als eins wird, nehmen wir nun wieder positive Glieder, so wie sie in der u-Reihe nacheinander kommen, ohne eines zu vergessen, und zwar so viele, daß dadurch die Teilsumme gerade wieder größer als eins wird. · zu Dann kommen wieder einige neganehmen. Dann wird s4 tive Glieder, doch nicht mehr als nötig sind, um die Teilsumme gerade kleiner als eins zu machen.
