(as many) Parts unequal in FA, or hd.
- But, what is the Proportion of r to 1, or (which depends on it) of 1 - r to 1, or 1 to m; remains to be inquired by Experiment?
- If the Progression be not infinitely continued; but end (suppose) at N, and its least Term be A = MN; then, out of
V / R - 1 = 1⁄m + 1⁄mm + 1⁄m3, &c. is to be subducted
A / R - 1 (as at ¶ 10.) that is
(as by Division will appear) A⁄R + A⁄R2 + A⁄R3 &c. That is (in our present Case) a⁄m + a⁄mm + a⁄m3 &c. And so the Aggregate will be
1-a / m +
1-a / mm +
1-a / mmm &c. =
1-a / n.
And thus as to the Line
