Concept explainers
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

[3]arrow_forwardThe numbers in the sequence 1,3,6,10,15,21... are called as triangular numbers. Determine the 15th triangular number? Select one: a. 55 O b. 78 O C. 120 O d. 105arrow_forwardRyan is building a triangle sequence so that one triangle is added to the right each time, as shown below. How many matchsticks will he use for the nth figure and for the figure one before the nth? Click the icon to view the matchstick square figures. The nth figure will take matchsticks to build. (Type an expression using n as the variable. Simplify your answer.) The figure one before the nth figure will take matchsticks to build. (Type an expression using n as the variable.
