If you analyze the results of draws, you will notice that for many numbers in the previous draw, quite certain numbers fall more often than others. Such numbers are called precursors.
That is, if a lot of Powerball draws have a number 36 and the next draw has a number 21, then number 36 is the precursor for number 21. Spending a little time analyzing the results of draws, you can catch two or three dozen pairs of precursor-follower. Subsequently, this list can be updated and supplemented, it will often bring you 2-3 numbers for the next game, if in the last draw their precursors fell out. Sometimes a number is a precursor for itself, which means that this number is just a fan of repeats, we have already encountered this.
