C Correct answer
Explanation

Each term is n×(n+1): 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30, so 6×7=42.

AI explanation

The differences between consecutive terms are 4, 6, 8, 10 — increasing by 2 each time. Following this pattern, the next difference should be 12, so the missing term is 30 + 12 = 42.
