The -exec option executes the following command on a target of the 'find' command.
Unix files do not rely on extensions, therefore there is no command to find them.
Some examples of the Unix find command are "find . -print" or "find /-name foo". One other command could be "find /home/wpollock/foo" or "find /tmp /var/tmp. $HOME -name foo".
There is no traditional 'execute' command in Unix.
I don't know about a SEQ command, but the 'seq' command in Unix will print a sequence of numbers from first to last, with a given increment. Use the 'man seq' command to find out how to use it.
There is no standard 'format' command in Unix.
