$$\lim_{n\to\infty}\frac{(2n-1)!}{3^n(n!)^2}$$

How can I associate limit problem with series? And how can i find limits from series? Can anyone help?

    Please write the formula using [LaTeX](http://meta.math.stackexchange.com/questions/107/faq-for-math-stackexchange/117#117), otherwise it is unclear what you mean.2012-12-25
