Question

I don't understand 2.

Answer 1

From what I see in the question, I think you need to use the rule which is ÷5 by the "in" numbers.

So for no.2, it would be 15÷5 which is 3; 20÷5 = 4; 35÷5 = 7; 10 (I think thats the number because your hair is blocking it) ÷5 = 2. Hope this helped!

Answer 2

Add the in number to the start of each rule and that is your out.
