I'm reading this book called "Tonal Harmony" and I'm not sure about the answer to the 15th question.
The notes in question 15 are A3, C5, A4 and D4, which is D Mm7 chord, (D F# A C), with A3, the fifth in the bass.
A seventh chord with the fifth in the bass would be second inversion right? which is 4 3
But the answer the textbook has near the end says it's 6 5, which is first inversion. Am I missing something here?
