Suppose there is a jar capable of containing infinitely many marbles and an infinite collection of marbles labelled 1, 2, 3, and so on. At time "t" = 0, marbles 1 through 10 are placed in the jar and marble 1 is taken out. At "t" = 0.5, marbles 11 through 20 are placed in the jar and marble 2 is taken out; at "t" = 0.75, marbles 21 through 30 are put in the jar and marble 3 is taken out; and in general at time "t" = 1 − 0.5"n", marbles 10"n" + 1 through 10"n" + 10 are placed in the jar and marble "n" + 1 is taken out. How many marbles are in the jar at time "t" = 1?
