hmm i haven't done calculus for a while but isn't this a basic limits of infinite sequences or series?
ie sequence a is something like = 10n - n
the sequence b is something like = 10n-n as well ??? although for the first sequence you basically put 10 marbles in and take one out every second, and then in the second you put 10 in, although the rate at pulling out every tenth marble is not specified?
the way i have defined it, the 2 series converge or approach to infinity as n approaches infinity, ie the equations both equal 9n, the same as CSflim.
you say the answers are different how do you know?
also excuse my calc if it is a bit off, i haven't done it for a while...
