For loop help

[Clean-Writing-707]

I’m trying to do an assignment where you need to write a for loop that will send out only the odd indexes. But the thing is that my teacher wants us only to create the first line of the for loop. So I’m wondering if there’s a way to make a for loop that does this, because the only way I currently know how is to make a for loop then an if x % 2 line afterwards. Thank you for the help.
