Bash Script: Build loop script with changing value

Job ID: 30635975

Budget: $10 – $30 USD

So i need loop script that can run my other script, this is the script

./engraver_cpu --n 4000 --path /plot1 --id 13790008575625040224 --sn 123
&& ./engraver_cpu --n 4000 --path /plot2 --id 13790008575625040224 --sn 456

i need the number 123 and 456 be changing every loop happen. lets say it will add 200 every loop happen
so
1st loop 123 and 456
2nd loop 323 and 656
3rd loop 523 and 956
etc

If this cant be make using bash script you can use any other ways, as long its editable and can be run in linux

PS: I will lend you my VPS to do this project if needed
