    Unhappy Precal exam in 4 hours and stuck on a partial sum problem

    Sorry, first post here, try my best!

    a_n=log((n+5)/(n+6))

    I understand how to do partial sums and all but throwing a log in there has stopped me in my tracks. Please help!

    Since \log \frac{n + 5}{n + 6} = \log (n + 5) - \log (n + 6) the partial sum will simplify to only two terms.
