<image>Arrange the consecutive odd numbers 1, 3, 5, 7, 9...79 into a table as shown in the diagram.

(1) What is the relationship between the sum of the five numbers in the cross frame shown in the diagram and 27?
(2) If the cross frame is moved left, right, or down, it can still enclose another five numbers. If the sum of these five numbers is 305, what is the middle number?
(3) Can the sum of the five numbers in the cross frame be equal to 210? If so, please write out these five numbers. If not, explain your reasoning.
