GEOMETRIC EXERCISES 54 mined as in Fig. 41. Here OPlt OP% 0P8, 0P±, and OP5 form a geometric series, the common rate being OPi : OP2- … Fig. 41. If (9T5! be the unit of length, the series consists of the natural powers of the common rate. 109. Representing the series by a, ar, a?-2, . . . . P1Pi=±aVl-\- PiPt=rarVl + t*. PzPi = ar*\'l + r*. These lines also form a geometric series with the common rate r. no. The terms can also be…
