A definition of right-continuous using monotone sequences.

The definition of $L = lim_xdownarrow y f(x)$, is that $f(x_n)to L$ as $ntoinfty$ for all sequences $x_n_ninmathbbNto y$ with $x_n>y$.



Is there a reference or a proof that this definition is equivalent to that using monotone sequences decreasing to $y$, that is:



$f(x_n)to L$ as $ntoinfty$ for all sequences $x_n_ninmathbbNdownarrow y$?
