point A is 2.50 m from +3.73*10^-8 C charge, and point B is 1.00 m from the charge.?
what is the potential difference when you go from point A to point B?

From A to B the potential increases (moving towards a positive charge) so you expect a positive value for the answer.
ΔV = VB - VA (that's the correct formula going from B to A)
= kQ/rB - kQ/rA
= kQ(1/rB - 1/rA)
= 8.99*10^9 * 3.73*10^-8 (1/1.00 - 1/2.50)
