for loop syntax

hi,

I have to use for loop in my script. The below code is providing an output,
1,2,3,4,5..n. But i need to display the values one by one eg: it has to display the first value then exit from the loop and display the second value then exit till n(last value).

for i in 1,2,3,4,5..n
  do                 
     echo $i
   done

Please suggest me ........

Leave all comma out:

for i in 1 2 3 4 5 6 7 8 9 10
  do                 
     echo $i
  done

#or

for i in {1..10}
  do                 
     echo $i
  done

for ((i=1; i<=10; i++))
do
    echo $i
done
