If the smallest of the three consecutive even numbers is a, then the largest is a______ The sum of these three numbers is______ ．

If the smallest of the three consecutive even numbers is a, then the largest is a______ The sum of these three numbers is______ ．

According to the given conditions, a is the smallest of the three continuous even numbers. According to the meaning and properties of the continuous even numbers, it is concluded that the two numbers after a can be represented by letters: a + 2, a + 2 + 2; then the three continuous even numbers are: A, a + 2, a + 4, and the maximum of them is a + 4; their sum: a + (a + 2) + (a + 4), = 3A + 6; so the answer is: a + 4, 3A + 6

If 3A = 5b, (a, B are not 0), then a: B=______ ．

Because 3A = 5b, then a: B = 5:3

The average of two consecutive even numbers is 17, and these two even numbers are ()

This is very simple. They are (16) and (18) respectively

A is an even number, and the two consecutive even numbers after a are______ 、______ The average of the three numbers is______ ．

(1) A is an even number, the two consecutive even numbers after a are a + 2, a + 4; (2) the average of the three numbers is: (a + 4 + A + 2 + a) △ 3, = (3a + 6) △ 3, = a + 2; so the answer is: a + 2, a + 4, a + 2

The average of four consecutive even numbers is 21

Let the first even number be a
a+[a+2]+{a+4]+[a+6]=21*4
4a+12=84
4a=72
a=18
So these four numbers are 18 20 22 24

The sum of 5 natural numbers is (2) the average of 5 natural ripening is (3) the sum of 5 continuous even numbers is (4) the average of 5 continuous odd numbers is (3)
Algebraic expression

Let the middle number of five continuous natural numbers be a
Then (1) the sum of five natural numbers is 5A
(2) The average of five natural ripens is a
Let the middle number of five consecutive even numbers be n
Then the sum of five consecutive even numbers is 5N
Let the middle number of five consecutive odd numbers be m
Then the average of five consecutive odd numbers is m

All in all
Even - even = even
Odd × odd = odd
Odd odd = even
Odd + even = odd
Even × even = even
Even + even = even
Odd even = odd
