Please use n for three consecutive even numbers (n is a natural number), and their sum is. Use M for two consecutive odd numbers (M is a natural number), and their sum is The two questions are irrelevant If there are three consecutive even numbers, whether there must be two consecutive odd numbers satisfying the upper number filling method, if there must be, please explain the filling method: if not, please explore and give the conditions that the number in the middle of the three consecutive even numbers must exist

Using n to represent three continuous even numbers is 2n 2n + 2 2n + 4
The sum of them is: 6N + 6
The sum of two consecutive odd numbers 2N-1 2n + 1 is 4N
