There are 4 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 the odd numbers is 6 less than the average of the even numbers. If the sum of the three even numbers is less than the sum of the four odd numbers, what is the average of x_{1}, x_{2}, x_{3 }and x_{4}?
