@teresarisa,
Honestly I don't want to give it away entirely because it took me quite some time to figure out all on my own. But I will definitely try to point you in the right direction as much as I can.
Look through the answers for the past LCs and compare them to the numbers in the sequence. Remember how those numbers are manipulated when you find them. Once you do that and get the first 4 numbers down, look at the LC round numbers. You should be able to find a pattern that is not that complicated - I overlooked it at first and started doing some ridiculous things before I got the pattern to finish the sequence. This explanation should make sense (I hope) if you're looking at the right numbers.
