    Limit...

    \lim [\frac{10^n+1}{2*10^n-1}]

    here is my work:
    \lim \frac{10^n(1+1)}{10^n(2*1-1)} = \frac{2}{1}
    But that was wrong..correct answer was \frac{1}{2}

    There is a mistake when you factorized : 10^n+1 = 10^n\left(1+\frac 1{10^n}\right)

    Assuming \color{blue}n\to\infty:
    Devide top and bottom by \color{blue}10^n.
