Show what the final output of this function will be. The answer will be in the form x * Z - y

Private Function F(x as Int, y As Int, z as Int)
If (y = 1) then
Return 2
Else
Return x * Z - y + F(x-1,y-1, z)
End If
End Function

if this is your code

Private Function F(x as Int, y As Int, z as Int)
If (y = 1) then
Return 2
Else
Return x * Z - y + F(x-1,y-1, z)
End If
End Function

what is your test data. if you test this code with y=1 then you will get an answer of 2, else Return x * Z - y + F(x-1,y-1, z)

The test data I'm using is y = 3. I tried using a trace table, but I get back to 2. Not sure how to get an answer in the form x * Z - y. Any help will be much appreciated.

Thanks
