D Correct answer
Explanation

The pattern follows the rule: each term is (previous term ÷ 2) - 10. Starting with 180: 180÷2-10=80, but the second term is 100. Checking the differences: 180-100=80, 100-48=52, 48-18=30, 18-4=14, 4-0=4. The second differences are: 28, 22, 16, 10, which decrease by 6 each time.
