First, hopefully you know what n! means.

For examples:
1! = 1
2! = 2*1 = 2
3!= 3*2*1=6
4!=4*3*2*1 = 24
5! = 5*4*3*2*1 = 120
etc.
n! = the product of the integers beginning with n and counting down to 1.

Now,
Beginning with n=1:
n=1, so
n=2, so
n=3, so
n=4, so
n=5, so

A1= 1!/1^2=1/1 = 1
A2= 2!/2^2= 2/4 = 1/2
A3= 3!/3^2= 6/9= 2/3
A4=4!/4^2= 24/16= 3/2
A5=5!/5^2=120/25= 24/5
