If a positive integer can be expressed as the square difference of two consecutive odd numbers, then the positive integer is called "extra odd number"
For example: 8 = 3 square - 1 square, 16 = 5 square - 3 square, 24 = 7 square - 5 square, so 8, 16, 24 are all odd numbers
(1) Are 32 and 2008 odd numbers? Why?
(2) Let two consecutive odd numbers be 2N-1 and 2n + 1 (where n is a positive integer). Is the special odd number constructed by these two consecutive odd numbers a multiple of 8? Why?

(1)9^2-7^2=81-49=32
(2n+1)^2-(2n-1)^2=8n=2008
n=251
So 32 and 2008 are very odd numbers
（2）(2n+1)^2-(2n-1)^2=8n
The special odd number constructed by these two continuous odd numbers is a multiple of 8
