Homework Help: math (Gaussian n! formula)

Posted by John on Saturday, October 2, 2010 at 7:23pm.

I'm trying to figure out the generalized form of the Gaussian n-factorial (n!) formula.

I keep seeing n!= n(n+1)/2 but that's not working.

For example: 5!= 120 but 5(6)/2 or 6(5/2) is 15; a far cry from 120. I don't understand what I'm doing wrong; distributing gives (n^2+n)/2 which is incorrect.

Also the example I saw as the supposed true story used 1-100 and showed it as 101(100/2) = 5050.

What am I missing here?
