For blue: You can see the difference between 59, 66 and 73 is 7. Using that logic, the missing number is 80 (73 + 7 = 80; 80 + 7 = 87)
For red: When you look at the difference between 06, 10 and 12 you can see it decreases (or increases depending on the way you’re reading it) by 4 then 2. So you can assume that the difference before that are 6 and 8 (12 – 2 = 10; 10 – 4 = 06; 06 – 6 = 0; 0 – 8 = -8)
So I think the number you’re looking for in the radio sheet is **0080** or maybe **8000**.

First time I’m seeing a negative number.
