The terms of a particular sequence are determined according to the following rule: If the value of a given term t is an odd positive integer, then the value of the following term is 3t -9; if the value of a given term t is an even positive integer, then the value of the following term is 2t -7. Suppose that the terms of the sequence alternate between two positive integers (a, b, a, b, ... ). What is the sum of the two positive integers?

Could you solve it quick please!!

Thank you so much!
