This might help the bash scripting newbies.
Here are some different ways of writing for loop in bash. The below one liners are just to show the loop iteration, does nothing significant !
$ for((i=1;i<=16;i+=2)); do echo $i; done
way2: jot is a command to print sequential or random data
$ for i in $(jot - 1 16 2); do echo $i; done
way3: seq prints sequential numbers
$ for i in $(seq 1 2 16); do echo $i; done
$ for i in `seq 1 2 16`; do echo $i; done
way4: Or if you want to explicitly write the for loop argumnets.
$ for i in 1 3 5 7 9 11 13 15; do echo $i; done
