Why is the sum of four consecutive numbers always even?

If n is the first number, n + n + 1 + n + 2 + n + 3 will be the sum, which is 4n + 6. 4n is always even, and 6 is even. Therefore, the sum of four consecutive numbers is always even.

Is it possible for four consecutive numbers to equal 39?

No.Any four consecutive numbers must contain two even numbers and two odd numbers.Adding two odd numbers together always gives an even number.Adding two even numbers always gives an even number.To end up with an odd number you need to add and odd number of odd numbers (3 of them, or 5, 7 etc) together.The nearest ways to get four consecutive numbers to come close to 39 are ...* 8+9+10+11 = 38or * 9+10+11+12 = 42

Is the sum of four even numbers always a multiple of 4?

No, the sum of four even numbers is not always a multiple of 4.. For example, 4 + 6 + 10 + 14 = 34 which is not a multiple of 4 If you include an "odd" number of even numbers which are not multiples of 4, then the total will not divide exactly by 4. In the above example 6 = 4 + 2, 10 = 4 + 4 + 2, and 14 = 4 + 4 + 4+ 2, and the total of the odd number of twos will not divide by 4 All multiples of 4 are the product of 2 with another even number: (Let a multiple of 4 be 4k. But 4 = 2 x 2, so 4k = (2 x 2)k = 2 x 2k and 2k is an even number for all k.) Let the four even numbers be 2k, 2m, 2n, 2p for some k, m, n, p. Then their sum is 2k + 2m + 2n + 2p = 2 (k + m + n + p) = 2q where q = k + m + n + p. k, m, n & p can be even or odd. If one, or three, of these is odd, then their sum, q, is odd. To be a multiple of 4 the sum k + m + n + p (= q) must be even. If it is odd, then twice it will not be a multiple of 4. For example, if k = 1, m = 2, n = 3, p = 5, then the four even numbers are 2 x 1 = 2, 2 x 2 = 4, 2 x 3 = 6, 2 x 5 = 10 and their sum is 2 x (1 + 2 + 3 + 5) = 2 x 11 = 22 which is not a multiple of 4.
