 Finite Alternative Odd Power Sum

(October 15, 2006)
 
The sums of the following expressions are true for any positive integer n. 
 
1.      .
 
Example:
            Let n = 3, the left-hand side of the above expression is 1-3+5 = 3 and its right-hand side is –3(-1) = 3. 
 
 
2.      .
 
Example:
            Let n = 3, the left-hand side of the above expression is 1-9+25 = 17 and its right-hand side is –2(9)(-1) –1 = 17. 
 
 
3.      .
 
Example:
            Let n = 4, the left-hand side of the above expression is 1-27+125-343 = -244 and its right-hand side is [3(4) – 4(64)](1) = -244.
