No, it's the number hit two neighbours, in a progressive bet. (2+2+2+2 numbers bet);
For an example
number 14 hit, now number 14 two neighbours are bet; 14=> 20,31
number 5 hit, now number 5 two neighbours are bet; 5=> 10,24
number 33 hit, now number 33 two neighbours are bet; 33=> 1,16
number 16 hit, now number 16 two neighbours are bet; 16=> 24,33
OK, so now 8 numbers are bet. Now you double bets (+1u bet on all numbers) AND do 4 spins, then STOP. (Stop if hit before that ofcourse!) & Restart
In your example above what do you do if a number repeats while you are building the progression ie.
number 14 hit, now number 14 two neighbours are bet; 14=> 20,31
number 5 hit, now number 5 two neighbours are bet; 5=> 10,24
number 33 hit, now number 33 two neighbours are bet; 33=> 1,16
number 5 hits again
