the diagram shows part of a design made by toothpicks to form triangles, the top level has 3 toothpicks the second level has 6 toothpicks and the third level has 9 toothpicks and so on. which level will use 24 toothpicks

Let's see... Now the first level has 3 toothpicks and the second has 6.. 1:3 2:6 3:9 Now do you see some kind of trend to this?
