02x 29x = 15 so when you see 15x then you will see 02x or 29x appear after it before the 15 appears again. 

139 = 38 pair and 76 to show before 13/19 appears again  if you get a whole lot of 13 pairs after this number then just look for a double of 

113 or 133 776 766 or 119 944 994

282 = is going to produce 29x / 96x  99x/26x /66x

i may expand but getting to many extras opened so want to close this one for now
