The sum of five consecutive natural numbers is 30, and the middle natural number is (). The sum of three consecutive even numbers is 24, and the largest even number is ()

The sum of five consecutive natural numbers is 30, and the middle natural number is (6). The sum of three consecutive even numbers is 24, and the largest even number is (10)

The sum of three consecutive natural numbers is 72. What are the three natural numbers? If they are continuous even numbers, what are the three numbers?

① The other two are: 24 + 24 = 1;
② Let the even number in the middle be x, then these three continuous even numbers are X-2, x, x + 2
（x-2）+x+（x+2）=72，
3x=72，
x=24；
Then the other two even numbers are:
24-2=22，24+2=26．

Let n be a natural number, then the odd number is______ , even______ Three consecutive natural numbers are______ .

Fill in the following order: 2n + 1; 2n; N, N + 1, N + 2
