Cooke uses the fingering 5-4-2-1 for a root position dominant seventh chord in the left hand. One reason to use 4 instead of 3 on the third of the chord (B natural for G7 in C major) is it leaves the third finger free to "C" for common chord changes like G7 to C .
How do you resolve a dominant 7th chord?
Dominant seventh chords harmoniously resolve into a major triad via voice leading, wherein each note moves stepwise between chords. In the case of an E7 chord, the G♯ resolves up a half-step to the note A, and the D resolves a half-step down to a C♯. These are the first and third scale degrees of an A major chord.
