Answer:
15 meters
Step-by-step explanation:
Zeno's last jump was 2 meters, so another jump half as far adds 1 meter to the 14 m total.
After 4 jumps, Zeno would have jumped 15 meters from his starting place.

<em>Comment on the question</em>
The given distances give a total "after 3 jumps." The question asks for a total "after 4 jumps." It is not clear whether that is 4 jumps total, or 4 more jumps. In the above, we have assumed it is 4 jumps total.
