We are going to look at pick 4 and break it down to get another hit 

So lets pretend 1921 hit straight just like that (its my grandmothers birth year ) 

19 is just added as 9+1=10 which the pairs are  55,00,91,82,73,64,226,334, 05

so we can do two things with the number 21 we can say what numbers did not fall such as starting with zero 03,04,05,06,07,08,09 which does work however may take longer and with more variables than we need

or we can say 7x3 =21 and use the 7 sum and 3 sum to get our last followers from it 

7= 70, 61,52,43,223,115

3= 30, 21

So look in your state see when the last time 1921 hit straight like that and what numbers above were produced . It may have no been the next draw but it was most likely there  in my mix of numbers .Going to see if NC got this number well we've never gotten it straight let me search other states we find it in Arkansas on Dec 1
