which number and why
1,9, 1,8, 1, maybe next should be 743, so first digits: 1,9,1,8,1,7 Of course that is wrong but it looks nice.

More than a nice try. That is the thing with these kind of puzzles, more than one potential answer, just not the one the puzzler was looking for, but just as valid.

yes and I should have been aware of this when selecting those numbers

my fault
and so I will give the answer

all numbers except one are times which can be displayed on a digital clock

the first set 861 does not belong and in the second set 372 does no belong
