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)

    = 201volts
