Circle of People Answer - A Thinking Ape challenge

• 

  Formula (latter entered into excel)

• 

  Sketch trying to visually break down the problem

Gathering initial data

I took initially a brute force approach to see the possible results for a range between 3 and 12 for N (image attached)

The formula

After analyzing the results I began working on a formula that could give the answer on all possible values for N (image attached)

Testing

With the formula in hand it was time to test the results with a broader range of N values. For this step I used Excel.

_ It was a very interesting challenge, I hope to hear again from you _

Thanks!
