Two |
To geue tow infinite progressions, of which one to be |
increasing & the other decreasing; that the totall summes |
may be aequall. ||
Although the nomber of the places <termes> be infinite, the last |
terminus of both muste be a quantity & finite. ||
To get the summe of an infinite progression is easy; but of a finite is to |
be don thus besides other wayes; but this way will serue in may many cases |
when others will not. especially in bynomialles. ||
The finite progression vnderstand to runne infinite & get the summe |
Then when the finite progression did do end get two or three nombers more in |
progression & from thence the get the summe of the infinite residue; the difference |
