Example 1

Suppose you are stacking pennies in a pyramid with a triangular base. How many pennies would you need to make a pyramid that is 10 levels tall? Simplify the problem by finding how many pennies you need for a smaller pyramid. Then look for a pattern. (See the above link. Look for 7.10)   Continue the pattern.     A pyramid with 10 layers needs 220 pennies.
