Week 21- Challenge 5 – In Circles
Challenge page : http://www.ancientsocieties.com/in-circles/
The challenge text says Read down.
We have an image of a sort of metallic surface with 11 groups of numbers.
These numbers are :
The last one has a P, we will get back to this later.
The difference between the numbers is always 18 : 117-99 = 315-297 = 81-63 = 45-27 and if we consider 351-9 as angles, the difference is also 18, 18°.
When placing the angles on a circle, we can see sectors and if we generalize this process, we will get 20 sectors of 18° (20*18=360).
We can think about a dartboard since it has 20 sectors.
Reading the numbers in the dartboard from 63-81 to the bottom P 63-81, we get :
1 5 5 5 6 6 2 1 4 5 P1
The P at the bottom of the document + the emphasized READ in the challenge text make us think about a book page.
The 10 first numbers are an ISBN code (http://www.isbnsearch.org/) for the book Women of Consequence: The Colorado Women’s Hall of Fame
Searching that book on Google Books : http://books.google.fr/books?id=ER_kf0pWJZUC will give us the solution, as the page one (P1) is dedicated to a certain Clara Brown a philanthropist, which is the theme of the week.
The solution is clarabrown
