The definition of the product of n numbers is https://es.wikipedia.org/wiki/Productorio
x = 10 -1/n is the number generating function for j from 0 to n
Product function in VBA of all the numbers that are generated from that equation (x = 10 -1/n) is given by:
Function mo(J, n) As Double

Dim i As Integer
Dim x As Double

mo = (x^2)*y
For i = 2 To n
x = 10 - (1 / i)
y= 10 - (1 /( i-1))

mo = mo * (x^2)*y
Next i

mo = mo / ((x^2)*y)

End Function

I want the sum of [product (x^2)*y]*1/100 from i = 2 To n
Can someone tell me please how to calculate the sum above in vba/excel? in other words how do i calculate the sum of the(Function mo (x^2)*y])/100 described above from i = 2 To n ???
