Is he asking me out on a date or as friends?

This guy *Mike* invited me to a weekend lunch with him, after I’d realised I received an invitation to go bowling in a group with him and his friends and apologised, leaving him my number when I realised I’d forgotten to check my emails in time to agree or decline. This is a one on one invitation and he said he doesn’t know whether or not it’s a date. He wants to see what happens. Is that a date? Or not really?

It’s really not clear to me.
