Puzzling Asked on March 24, 2021
Just saw a Circle of numbers on my Whats App message (source not listed) which is as following
Arrange numbers 1 to 32 in a circle such that any two adjacent
(neighboring) numbers add up to a perfect square (like 1,4,9,16 etc). No
number can be repeated.
Without programing you can try that and get an answer.
There is a question on this site
Fourteen numbers around a circle
That puts 14 numbers around a circle where either the sum or the absolute difference between the neigboring numbers is a Prime number
Here is my question
Can you put numbers 1 to 32 (without repeating any number) in a circle such that the sum of the
neighboring numbers is a Prime Number?
So if any three numbers (clockwise or anti clockwise) are a,b and c then a+b and b+c must be a Prime. and so on.
You can either answer my question OR both the WhatsApp and my question together.
There may be more than one answer.
Here is one way to do it
