First Inversion (ii 6/5)

Root Position: Root position refers to arranging chords so that their root note is in the bass (lowest) position. This is considered standard positioning for most chords.

Second Inversion: Second inversion occurs when you rearrange a triad or seventh chord so that its fifth becomes the lowest note. In Roman numeral analysis, it is represented by adding 4/3 after the chord symbol.

Figured Bass: Figured bass is a system of shorthand notation used in the Baroque era to indicate chord inversions and intervals above the bass note. It helps performers understand how to realize the harmony from a given bass line.
