QUESTION!!!

Im so bored so I want to test your IQ level... If you get the question correct then I will answer yes on the reply post..

So here it is: I think it is just a simple question and everyone knows this:

Def add(x,y)
outcome=9
For i in range (x,y,4)
Outcome +=i
Return outcome
Print (add(4,19))
