How To Determine Your WordPress Version

WordPress version is easily determined at the bottom page of every administration interface. Also when logged in as the administrator, you can check the current theme and theres always a version number of the WordPress that ensures compatibility of the theme.

Another way is through the version.php file in the cpanel file manager, SSH or FTP client. You can always check this by viewing the wp- in the directory and the current wp-version is always displayed.
