Deduce a value for the Earth's gravitational field at a height of 400000m, using only the information in the table, and taking the direction away from the Earth as positive.
Please I need help with this question because I can't seem to figure out what's missing.

As in hint 4, they want you to estimate g from
dV = -g dr
So take the points either side of the point you want and get dV and dr from the changes/differences in potential and distance
