Missing Numbers: 56 84 ? 189 283.5 425.25?

Don't know about the first one but the second one is 133 the third is 110 and the fourth is 24. You just have to look for patterns. Write them down on a sheet of paper and see what you need to add to get the next one. Do this for each number and find the adding pattern. It sounds and looks harder than it actually is. I really hope this helped. Sorry I couldn't get the first one.
