So the first thing you have to do is look at the input and output values and find the pattern. This is probably the hardest part. So 32-12=20 and 14-12=2 so we found the pattern all you have to do is find whats missing. So we have a blank and then a 14, all you do is add 12 to the 14 to find the input so the input for that would be 26 and now to find the other missing term you subtract 12 and that gives you -22. I hoped that helped.
