Pardon me, I'm pretty new on the whole "part writing from figured bass".
Based on what I know, I believe that a 6th means 1st inversion? (correct me if I'm wrong)
However, here's what I don't get:

Are the roman numerals that I've wrote correct for the given bass? The key is in G minor. And the 2nd note is A. My first guess was writing ii diminished 6 because A is the 2nd scale degree on the key of G minor. But then I realized that a 1st inversion could mean that the A was inverted for that so therefore, it is F which is iv 6 (the one I wrote in the image).
Which one is correct?
