I have been grappling with the algorithm to sum up the following series,
arguably a very awkward one.

1/(1*1) + 1/(1*2) + 1/(1*2*3)+1/(1*2*3*4) + ... + to the 150th term.

It would appear something between a recursive and For/Next construct
might be required but I can't quite get my head around it. Here was my
attempt (using a Function) which failed with Run time "out of stack
space" error.

Function SumSeries(n)
For i = n to 1 step -1
s = s + 1/(i*i-1*Sumseries(i))
Next
SumSeries = s
End Function

Sub test()
Msgbox Sumseries(150)
End Sub
