Professor told me he's not the best choice for a letter of recommendation, but that he can still write one. Should I still ask?

I need 5 letters of recommendation from professors to get my school's Health Professions Advisory Committee to review me. These letters need to come from science or math professors, and since I'm a liberal arts major my options are very limited. I have gotten 4 professors that know me well, but I had difficulty with coming up with a 5th. I decided to ask a professor whose class I did well in and really enjoyed. He told me that he can write me one, but it will mainly be based on my performance in the class and that they're usually looking for recommendations from people who know the student well. He said if I'd still like one to send him my transcript and resume. I'm completely fine with that, but I don't know if that was his way of saying he doesn't want to do it or if it's appropriate to tell him I'd still like one. I'm sure if he didn't want to he would've straight up said it, but I just wanted to confirm here what is and isn't appropriate. Thanks.

Take it at face value. Your professor will comment on the grade you attained in the class, your performance on a couple of assignments, as well as attendance and participation. 

Five is a lot of letters, so if your other 4 are more personal, it should be fine.
