Hi, I am doing a few exercises about figured bass.
The problem is that, on two exercises, there are the following 4 basses:
5 5 7 3
2 4 4
I do not have any idea about what kind of chords or which inversion they are: I searched for similar examples on my harmony book and google, I cannot find them.
I may guess that the latter indicates just a generic third interval and so there are many possibilities available (please correct me if I am wrong), but what about the first three? Thanks.
