What I did was make a table with 4 columns (the bulbs) and then 50 columns (the number inserted [1-50]) then test every number from 1-50 and tick the section with the number and the bulb. For example, when I put the number 19 in the machine, the blue bulb lights up, meaning I would put a tick in the box in the blue bulb column in the 19th row. After this, I went to a column and checked which numbers made it light up. For the blue bulb, the numbers were 1, 10, 19, 28, 37, and 46. As you can see, each number has a difference of 9 in between them. To fill out the answer pop-up, you had to check the gaps (for blue it was a gap of 9) and then put the number 9 in the 2nd and 4th boxes. The 2nd and 4th boxes are always the same. After, you need to work out how much less or more the number has to be to light up the bulb. For the blue one for me, it was the number had to be 1 more than a multiple of 9 or 8 less than a multiple of 9. 1 + 8 = 9 and this was the same situation for all the bulbs I completed. That means you only have to work out one of those two boxes to work out the other. Hope this makes sense!!
