    \[Sn=\frac{ 6 }{ 10 }+\frac{ 6 }{ 100 }+...\]

    is your job to add up \[\frac{6}{10}+\frac{6}{100}+\frac{6}{1000}+...\] which is the same as \[0.6666...\]

    you probably already know this one since \(0.33333...=\frac{1}{3}\) then if you double it you get \(0.6666...=\frac{2}{3}\)

    So it tends to 0.66666... in infinity?

    \(\overline{.6}=\frac{2}{3}\)

    i was assuming you knew what "point six" repeating is if you have so sum a geometric series, we can do that as well, but you are still going to get \(\frac{2}{3}\)

    I knew. So...its tendency and writing the series is the same?

    Oh... \[Sn?\frac{ 6 }{ 10 }\times \frac{ 1 }{ 10 }^{n-1}\]
