Let $f(x) = e^x - ax$, $g(x) = ax - \mathrm{ln}x$, $f$ shares the minimum with $g$.

1. Determine $a$
2. Prove that there exists a line $y = b$, such that there are three different intersections of $y = b$, $y = f(x)$ and $y = g(x)$, and the x-coordinates of these points form an arithmatic sequence
