and despite years of piano, 2-1-2-3-4-5-4 is easier to do smoothly (less hand motion) to get the hand into the final position of the right most 5 notes, as opposed to the other choices...
also, since scale training at playing a c-major or a-minor scale would typically be 1-2-3-1-2-3-4-5, we'll note that last 5 notes are 1-2-3-4-5...
I agree with whipartist and perspicuity: 2-1-2-3-4-5-4. And if I did need to start with 1 (depending on what might have come before), I'd go with 1-2-1-2-3-4-3 -- can't imagine why no one suggested this.

as marked, it should be played smooth...
