ANSWER- 62,525

 

 

EXPLANATION- To get to this # I started by drawing a layer of peaches just so I know the pattern of the increase of the outer peaches in each layer. I figured that the increase of outer peaches for every layer was 3. Then i used that information to get the # of outer peaches for each layer. Once i got all the numbers, I added them up and got 3,676. That # represents the total number of peaches on the bottom layer of the pyramid. Then I took that # and kept substracting the # of outer peaches and every # I got I wrote to the side. All the #'s I ended up with were the total # of peaches in each layer. Finally I added up all those #'s to give me 62,525, the total # of peaches in the 50 layered pyramid of peaches
