Hi @tony-crane73gmail-com , welcome to FW2. If you write out the chords in the G major scale as @Loraine has done above, you will see the order (or position) of the chords (and this applies to any major scale) from 1 through 7 using the Nashville numbering system where G is the 1 chord and Am is the 2 chord and so on. So in the Nashville numbering system, the 1, 4 & 5 chords are always MAJOR, and the 2, 3 & 6 chords are always minor, and the 7 chord is diminished (unless substituted). In the chord progression that you stated in your question, you’ll notice that they are all Major chords in the key of G major.

Hope that helps.
