Multiplication Pyramid

WALT: Find a rule to a sequential pattern

For this activity, we used our multiplication skills to find out the top number.  As you can see the numbers keep getting bigger and bigger.  How this pyramid works is that the numbers next to each other is multiplied by each other.  For example:

This 5 and 2 are multiplied by each other to make 10.

I did this all the way up the pyramid until I got to the number 192,756,122,160.  Also known as one hundred and ninety two billion, seven hundred and fifty six million, one hundred twenty two thousand and one hundred and sixty.
