Add them up and divide the sum by 2.

How can you determine wether a sum of several numbers such as 13 45 24 17 is even or odd?
Go through each of the numbers, and count how many of them are odd. If you count an odd number of them, then their sum is odd. If you count an even number of them, then their sum is even.
Is the product positive or negative when an even number of negative numbers are multiplied?
Any 2 negative numbers, whether even or odd, when multiplied are positive
What is the result of product of even numbers and odd numbers?
If you multiply one even number by one odd number, the result is always even. In general, if you multiply several numbers, and at least one of the numbers is even, the product is always even. This is because "even" means "multiple of 2", and if one of the factors contains a 2 as a factor, so will the product.
How can you use the prime factorization of a number to determine whether the number is even or add?
Very easily: if the prime factorization includes 2, it's even. If not, it's odd.
How many numbers are equal to the sum of two odd one-didit numbers?
You didn't state whether the two odd numbers to be added must be different odd numbers or whether they can be the same odd number. So I'll do both cases. Case 1: They can be the same odd number: They are all even numbers starting with 1+1=2 and ending up with 9+9=18. So you can get these 9 even numbers: 2,4,6,8,10,12,14,16,18. Case 2: They must be different odd numbers: If you require that the two single-digit odd numbers be DIFFERENT odd numbers, then you can't get 2 or 18, so you can only get these 7 even numbers 4,6,8,10,12,14,16. So the answer is either 9 or 7, depoending on whether the two odd numbers you are adding can or can't be the same odd number.
How would you determine whether the product of many natural numbers is even or odd?
If at least one of the numbers is even, the result will be even. Otherwise all the numbers are odd and the result will be odd.
How can you determine whether a sum of several is even or odd?
if there is an od quantity of odd numbers the sum will be odd....example 1 3 4 6 has two odds so it will be even =14 1 3 5 6 has three odds and it is = 15
What is the next number 2 7?
It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.
Can you tell if sum of several numbers will be even or odd?
Yes, all you have to do is to count the number of ODD numbers in the list. If it is odd, then the sum will be odd; if even, so will the sum. Knowing this can help you run a quick validity check when you sum up a list of numbers. (The method works because: a) the sum of two even numbers is even, and b) the sum pf two odd numbers is even, but c) the sum of an even number and an odd number is odd. Hence, if you only determine whether there are any unpaired odd numbers, you know the answer.)
Is the set of prime numbers well defined or not?
Well, there is a clear definition, and at least in theory you can always determine whether a number is a primer number or not, so I would say, yes.

Can you tell if the product of several numbers will be even or odd?
Yes it is possible to determine if a product will be even or odd. To do this, we need to consider what an even number is. Even numbers are numbers with at least one factor of 2 (meaning they are divisible by 2). Thus, any product of numbers which contains at least one even number will result in an even product. If all of the numbers being multiplied together are odd, the product will be odd. If one or more of the numbers is even, the product will be even.
Is the set of prime numbers is well defined or not and why?
The set is well defined. Whether or not a given integer belongs to the set of prime numbers is clearly defined even if, for extremely large numbers, it may prove impossible to determine the status of that number.
How could you determine whether a sum of numbers such as 127 plus 38 is even or odd?
The parity rules are: Odd + Odd = Even Even + Even = Even Odd + Even = Odd Even + Odd = Odd So the parity where one number is even is that of the other number. This means that you can go through a list of numbers and ignore all the even numbers. Every PAIR of odd numbers has even parity and by the previous paragraph, even parity can be ignored. So you can pair off odd numbers and ignore them.
Without building a tile model how can you determine whether a sum of numbers such as 127 38 is even or odd?
None Of Them Equals 100 and 10 so 127 is 130
Without building a tile model how can you determine whether a sum of numbers is even or odd?
You have to look at the ones place digit for the quick way to this. If both ones digits are even then it will be even, if they are both odd then it will be even, if one is odd and one is even then it will be odd.
How can you determine whether the sum of several numbers such as 13 45 24 17 is even or odd without actually calculating the sum?
Just add the end numbers, so 3 + 5 + 4 + 7 = 19 which is odd. Alternatively, ignore even numbers [such as 4], and two odd numbers [3 and 5] added always make an even number [8], which leaves and odd number [7] so the answer will be odd. Example; five hundred different numbers, where 483 are even and 17 are odd, then no matter what the actual 500 numbers are the answer will be odd, as there is an odd [17] quantity of odd numbers.
