Well that depends on your post per page settings:

AdminCP > settings > Options > Thread Display Options (showthread) > Maximum Displayed Posts Before Page Split

Maximum Displayed Posts Before Page Split
The number of posts to display on a thread page in linear or hybrid mode before splitting it over multiple pages.

Note: This number must be at least 1.

So if you have that set to 20 posts per page before the split simply use the code I just posted above and change the ? mark to 19 .

Example:

<vb:if condition="$post['postcount'] % $vboptions['maxposts'] == 19">
