Answer:

2624

Step-by-step explanation:

Let the second digit be X. Therefore the first digit would be (1/3)X. The third digit would be 8-X and the fourth digit would be 8-X+2 or 10-X.

The last hint is that all the digits add up to 14, so

(1/3)X + X + (8-X) + (10-X) = 14

Solving for X gets you X = 6. If you plug the X value back in to satisfy the conditions, you get 2624.
