Use inductive reasoning to predict the next line in the pattern. Then perform the arithmetic to determine whether your conjecture is correct.(1 × 9) - 4 = 5(21 × 9) - 4 = 185(321 × 9) - 4 = 2885
A. (4321 × 9) - 4 = 28,885 B. (432 × 9) - 4 = 38,885 C. (4321 × 9) - 4 = 38,885 D. (4321 × 9) - 4 = 3884
