Cannonballs can be stacked to form a pyramid with a triangular base. Five of these pyramids are shown below. Use these figures. The sequence formed by the numbers of cannonballs in the above pyramids is called the tetrahedral sequence. The nth-term formula for the tetrahedral sequence is T e t r a h e d r a l n = 1 6 n ( n + 1 ) ( n + 2 ) . Find T e t r a h e d r a l 10 .
