Best ResponseYou've already chosen the best response.1\[\frac{1r^k}{1r}\] if r < 1, then the limit as k to infinity is \[\frac{1}{1r}\]

Best ResponseYou've already chosen the best response.0but would it be possible to find the sum ?

Best ResponseYou've already chosen the best response.1let me rechk my thought tho ... S = r + r^2 + r^3 + ... + r^n rS =  r^2  r^3  ...  r^n  r^(n+1)  (1r)S = r + 0 .......................... r^(n+1) S= r  r^(n+1)  1  r

Best ResponseYou've already chosen the best response.1if r < 1 then that exponented part goes to 0 leaving us: S = r/(1r) for the sum

Best ResponseYou've already chosen the best response.1might be better stated the r < 1, but why nitpick

Best ResponseYou've already chosen the best response.1\[\frac{4}{.5}\sum_{{j}={1}}^{\infty}0.5^{j}\] \[\frac{4}{.5}~\frac{.5}{1.5}\] \[\frac{4}{.5}=8\]
