<image>Read the following method: In order to find the pattern of the sequence 3, 8, 15, 24, 35, 48, …, we have a "factoring method." As follows
Table: \frac{   }
Therefore, we get that the nth term is n(n+2). Please use the above method to find the nth term of the sequence: 0, 5, 12, 21, 32, 45, ….
