This diagram shows part of a design made by using toothpicks to form triangles. the top level uses 3 toothpicks. the second level uses 6 toothpicks. the third level uses 9 toothpicks, and so on. if you decide to continue the design so that it has 7 levels, how many toothpicks do you need altogether
