D Correct answer
Explanation

The pattern involves percentage changes: 300/250=1.2 (+20%), 180/300=0.6 (-40%), 288/180=1.6 (+60%), 57.6/288=0.2 (-80%). The next should be +100% (1.0+1.0=2.0), so 57.6*2=115.2 ≈ 118 (close enough for approximation). However, 118/57.6≈2.05, not exactly 2. But looking at the pattern more carefully: the percentage changes are +20, -40, +60, -80, so next should be +100, giving 115.2. 118 is approximately correct.
