Finding a Maclaurin series for ln(x)

Since ln(0) doesn't exist, this question is futile right?

I am tasked with finding a Maclaurin powerseries for ln(x) and to find out how many times I have to run that series to get a accurate answer for ln(1.5).

What should I do? Should I find the taylor series for ln(1.5) for should I find the Maclaurin for ln(1 + x) and find out what .5 is instead of 1.5.

Thanks.

Seems like the better choice (Maclaurin for $ln(1 + x)$ or Taylor of $ln(x)$ about $x=1$) - this may be what was intended all along. However, you should clarify with instructor.
