Starting from 2, continuous even numbers are added, and the sum is as follows: 2 + 2 = 2 × 22 + 4 = 6 = 2 × 32 + 4 + 6 = 12 = 3 × 42 + 4 + 6 + 8 = 20 = 4 × 5 (1) What is the sum of N consecutive even numbers from 2? (2) Take n = 6 to verify whether the conclusion of (1) is correct

（1）2+4+6+… +2n = n (n + 1); (2) when n = 6, according to the law, it should be 2 + 4 + 6 + 8 + 10 + 12 = 42 = 6 × 7, according to (1) 2 + 4 + 6 + 8 + 10 + 2 × 6 = 6 (6 + 1), it is consistent
