Question
The pattern of numbers you should have come up with in the Project Development in lesson 1.03 about tetrahedron kites is 1, 3, 6, 10, 15, 21,..(if you didn't get that, you may try
drawing a picture to count the kites).
This sequence of numbers is called the triangular numbers and is very common in real world mathematics. Search on the internet for a formula that gives you the nth triangular
number. In other words, we are looking for a formula with n such that when you put 1 in for n you get the first triangular number, 1. When you put 2 in for n, you get the second
triangular number, 3. When you put in 3 for n you get 6, for 4 you get 10, and so on.
Write your formula in the question below.
Give an explanation as to why you think the formula is what it is.
