A Correct answer
Explanation

The series 2, 6, 36, 60, 130, 210 follows a pattern involving cubes and differences. Comparing 1³+1=2, 2³-2=6, 3³-3=24 (not 36), 4³-4=60, 5³+5=130, 6³+6=222 (not 210), the number 36 breaks the pattern. The expected third term following 1³+1 and 2³-2 should be 3³-3=24, not 36.
