In order to 
get the fame general rule as that given above in the cafe of B 
or C’s being the oldeft of the three lives, it is to be oblerved, 
that the firft five expreffions, by the fecond part of the folution 
of Prob. i. appear to be = 1 ~ ABC -- M + E. And (lup- 
pofing r to reprefent the value of 3 on the contingency of As 
dying after C) that the laft three expreffions appear to be 
r - i . A-AC 
. But Eis = R + 
r- I . B-AB

he=' — — — — A - -r; therefore, the fum of the above 
expreffions may be eafily found — s • r ~ 1 • bC - AB c + R + \y 
-M. 
If the three lives be of equal age, the value of the rever- 
fion will be = — — — xV-L. This expreffion may be de-
