To determine Terry's total displacement, we need to consider the distances he traveled in both the east and west directions.
1. Terry first walks 3 blocks east: +3 blocks
2. Then he walks 2 blocks further east: +2 blocks
3. Finally, he walks 4 blocks west: -4 blocks
Now we can calculate his total displacement:
Total Displacement = (3 + 2 - 4) blocks
Total Displacement = 5 - 4
Total Displacement = 1 block
Therefore, the correct answer is: **D. 1 block**.
