in what increments do they go in size for eg. my stock jets are 148.8 and 150
does 150 come after 148.8 or is there one in between
 

none in between.

aftermarkets go 145/147.5/150/152.5/155 and so on.
yamaha ones go in weird incriments that coincide with jets they needed for different model sleds. some of them coincide and some fill in between the aftermarkets.
 
Yamaha jets are 0, 1.3 ,2.5 3.8, 5, 6.3, 7.5, 8.8 Just add the 1st 2 didgits to these #. Yamaha call them 1/4 jets the ones with the .3 and .8's .........SRXtreme
