Study the following code carefully don't hand it in until you (a) understand each point and can explain why each piece does what it does and (b) in a separate notebook you can recreate it from scratch:

Do[
 If[(Mod[n, 2] == 0) || (Mod[n, 5] == 0), Print[n]],
 {n, 1, 30}
 ]

What have you tried? It's probably not in the cards to use this forum to have us do your homework for you ;-)
