-The law of 1 2 - 3 4 - 5 6 is expressed by n

-1 = 1X (-1)^1 = 1 X (-1)
2 = 2 X (-1)^2 = 2 X (-1)(-1) = 2 X 1
-3 = 3 X (-1)^3 = 3 X (-1)(-1)(-1) = 3 X (-1) X 1
4 = 4 X (-1)^4 = 4 X (-1)(-1)(-1)(-1) = 4 X 1 X 1
-5 = 5 X (-1)^5 = 5 X (-1)(-1)(-1)(-1)(-1) = 5 X (-1) X 1 X 1
……
The odd power of (- 1) is - 1;
The even power of (- 1) is that negative gets positive and becomes positive 1;
The regular expression of these numbers is n x (- 1) ^ n
