B Correct answer
Explanation

Analyzing the series: 18000 to 3600 (÷5), 3600 to 720 (÷5), 720 to 142.2 (should be ÷5 = 144), 142.2 to 28.8 (÷4.94 ≈ 5, but should be ÷5 = 28.4), 28.8 to 5.76 (÷5). The pattern is division by 5. 142.2 is wrong because 720÷5 = 144, not 142.2. Additionally, 28.8÷5 = 5.76, so if 142.2 were correct, 28.8 would be 142.2÷5 = 28.44, not 28.8. The claimed answer B (142.2) is correct.
