I started by choosing two random numbers that added up to 15 (8 and 7).
I then put a 13 in the next box because 7 and 13 is 20.
I then put a 10 in the next box because 13 and 10 is 23.
I then put a 6 in the next box because 6 and 10 is 16.
I am now half way.
I then put a 12 in the next box because 6 and 12 is 18.
Finally, i put a 9 in the next box because 12 and 9 is 21.
If it did not work i would start again with different starting numbers.
