This seems to be in the new synchronization

The number matrix shown in the figure is composed of 50 odd numbers

(1) What is the relationship between the four numbers in the box?
(2) In a number matrix graph, make any box similar to that in (1), and let the number in the upper left corner be X. then how can the other three numbers be represented?
(3) If the sum of the four numbers in the box is 200, can we find the four numbers?
(4) Are there four numbers in the box so that their sum is 382?

1) What is the relationship between the four numbers in the box?
25-13=27-15
(2) In a number matrix graph, make any box similar to that in (1), and let the number in the upper left corner be X. then how can the other three numbers be represented?
x,x+2,12+x,14+x
(3) If the sum of the four numbers in the box is 200, can we find the four numbers?
4X + 28 = 200, x = 43: 43, 45, 55, 57
(4) Are there four numbers in the box so that their sum is 382?
4X + 28 = 382 x is not a natural number, so it doesn't exist

The number matrix of the graph is composed of odd numbers
(1) If the sum of four numbers in such a box is 324, find the number;
(2) Is there such four numbers whose sum is 220? Why?

3, 5, 13, 15 are framed

1) Let the upper left corner be x and the four numbers be
x,x+2
x+10,x+12
Sum, 4x + 24 = 324, x = 75, verify, can be combined into a box, so exist, for 75
2) The same, 4x + 24 = 220, x = 49 verify, 49 in the last side, four numbers can not form a box, so it does not exist

The number matrix of a graph is composed of odd numbers. (1) what is the relationship between the four numbers in the frame of a graph? (let the first number in the first line of the box be x) (2) if the sum of the four numbers in the box is 200, then find the four numbers; (3) is there any such four numbers, and their sum is 420, why?

(1) Let the first number in the first row be x, then the other three numbers are x + 2, x + 8, x + 10 in turn. (2) according to the meaning of the question, we get x + X + 2 + X + 8 + X + 10 = 200, the solution is x = 45, ∧ the four numbers are 45, 47, 53, 55 in turn. Answer: the four numbers are 45, 47, 53, 55 in turn. (3) does not exist. ∫ 4x + 20 = 420, the solution is x = 100, which is even and does not exist
