Two weeks ago we posed a puzzle about Ferrero Rocher chocolates.
In that puzzle we asked the number of chocolates in a pile ten layers tall where the pile was a tetrahedron. That is with one chocolate at the top resting on three chocolates in the layer below, and so on.
And we followed this by asking if there was a formula for a pile of any height.
This week we have changed the pile to a Pyramid. That is with one chocolate at the top resting on four chocolates in the layer below, and so on.
So how many chocolates are in a pile ten layers tall?
And following on from this, is there a formula to calculate the number of chocolates in a pile of any height?
