Estimation of Candles arranged in a pattern

Can you estimate the number of candles which are
arranged in a particular pattern.

In the attached video, I have explained the calculation of actual count using matrix.

I also added a link to the worksheet where I calculated the total.  Please click this link.

    1. Brilliant! That shows the working out so clearly! I wonder if other people will estimate the number of candles, or whether they'll work it out carefully like you?

  6. An excellent question. Super explanation of how it was set out and the total calculated. This will be really useful when we look at square numbers too. Well done.
