19 numbers are written on a circumference of a circle, in any order.
Their sum is 203 and the biggest number is X.
Any 3 adjacent numbers sum up to 31 or more.
What is the maximal possible value of X ?
If this number is selected, what can be said about the other 18?

Another way to see no other number can be greater than 17 is that any point can be the one outside the 6 triplets. Thus every point must be at most 17.
