✔ 最佳答案
Wrong picture, anyway, the final position of x-coordinate is :100 - 25 + 25/4 - 25/16 + ...
= 100 / [1 - (-1/4)]
= 80
y-coordinate is :
200 - 50 + 25/2 - 25/16 + ...
= 200 / [1 - (-1/4)]
= 180
Therefore, the final position of the ant is (80, 180).

Sorry, y-coordinate is 160.
The final position is (80, 160)
