At the end of a seminar I wish to ask audiences that they can ask me questions if they have any. How do I say this in a professional and attractive manner?
The most important thing is to finish well. Signal clearly that you are coming to the end of your talk, using 'lastly,, 'I would like to end by saying', etc, so they know that you are finishing, then just thank them for their attention and offer to answer questions. That's it.
