Use inductive reasoning to predict the next line in the pattern. Then perform the arithmetic to determine whether your conjecture is correct.8 × 9 = 10 × 11 - (8 + 9 + 10 + 11)9 × 10 = 11 × 12 - (9 + 10 + 11 + 12)
A. 10 × 11 = 12 × 13 - (10 + 11 + 12 + 13) B. 10 × 11 = 12 × 13 - (8 + 9 + 10 + 11 + 12 + 13) C. 11 × 12 = 13 × 14 - (10 + 9 + 8 + 7) D. 11 × 12 = 13 × 14 - (11 + 12 + 13 + 14)
