Ok, first thing you need it that exercise is to create an array and fill it 
with values:
    
    
    var a: array[10, int]
    for i in 1 .. 10:
      a[i-1] = 10*i
    
    
    Run

Now comes the part you're struggling with:
    
    
    for i in 0 .. 9:
      if i mod 2 != 0:
        echo a[i]
    
    
    Run

There are of course (as shown above) other ways to do it, but this is how I (if 
I were a beginner :)) would do it.
