If you are referring to highway routes, north-south routes have the odd numbers.

The sum of two odd numbers is always even; the sum of three odd numbers is always odd; the sum of four odd numbers is always even; the sum of five odd numbers is always odd; etc
The sum of two odd numbers or two even numbers is an even number. The sum of an odd number and an even number is an odd number.
If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = even)
If you are referring to highway routes, north-south routes have the odd numbers.
North-south = odd numbers. East-west = even numbers.
On the U.S. interstate system, even numbers indicate East/West routes; Odd numbers represent North/South routes; 3 number routes generally indicate belt-routes or local alternates.

There is no such pattern because there are no even odd numbers. Odd numbers, by definition, are odd and therefore, not even.
The answer depends on how many odd numbers are being added together: even numbers make no difference.If the count of odd numbers is odd then the total is odd, andff the count of odd numbers is even then the total is even.
Multiply two odd numbers Add an even and an odd Subtract an odd and an even
Always. even + even = even odd + odd = even even + odd = odd odd + even = odd To summarise, if you add like numbers you get even, otherwise you get odd.
The sum of two odd numbers is always even; the sum of three odd numbers is always odd; the sum of four odd numbers is always even; the sum of five odd numbers is always odd; etc
The product of two odd numbers is always odd.
The product of multiplication results in a number that has all of the factors of the two numbers being multiplied. All even numbers have the prime factor 2. Since no odd number has the factor 2, no product of those numbers can have it. So: - Odd numbers times odd numbers produce odd numbers. - Odd numbers times even numbers produce even numbers. - Even numbers times even numbers produce even numbers.
The sum of two odd numbers or two even numbers is an even number. The sum of an odd number and an even number is an odd number.
