There are four consecutive odd numbers \(x_1, x_2, x_3\) and \(x_4\) and three consecutive even numbers \(y_1, y_2\) and \(y_3\). The average of odd numbers is 12 less than the average of even numbers. If the sum of three even numbers is 32 less than the sum of four odd numbers, then the average of \(x_1, x_2, x_3\) and \(x_4\) is
