I tried your code i added this at the end

puts(num)

i have this :

21
41
61
81
101
1

and  i think its a correct response because we have two variables one 
have the scope in the block who have at the end of iteration 5
the other variable have the value 1 witch is displayed

sorry for my bad English :(
