Let's denote the digit in the hundredth place as H, the digit in the tenth place as T, and the digit in the unit's place as U.

From the problem, we know that:

1) H = T + 2
2) U = T - 2
3) H + T + U = 18

We can substitute the first two equations into the third to get:

(T + 2) + T + (T - 2) = 18
3T = 18
T = 18 / 3 = 6

Substituting T = 6 into the first two equations, we get:

H = 6 + 2 = 8
U = 6 - 2 = 4

So, the number is 864. Therefore, the correct choice is 864.
