Question 22
Forgetful Rio is lost in an ancient tomb. Twelve doors form an arc, and only door 11 is an exit. Each door has a numerical code. Rio remembers that door 1 has code 5, door 12 has code 9, and the codes of any three consecutive doors sum to 22.
1. Find the sum of the codes of doors 2 and 3, and the code of door 4.
2. Find the sum for doors 5 and 6, the code of door 7 and, similarly, the code of door 10.
3. Find the code of door 11 so Rio can escape.
