Explanation

Pattern: multiply by n and add n, starting from 12. 12 × 1 + 1 = 13, 13 × 2 + 2 = 28, 28 × 3 + 3 = 87, 87 × 4 + 4 = 352, 352 × 5 + 5 = 1765, 1765 × 6 + 6 = 10596. But series shows 246 instead of 352 at the 4th position, making 246 the wrong term. The pattern consistently applies n × previous term + n.
