How can you determine weather a sum of severals numbers such as 13 plus 45 plus 24 plus 17 is even or odd?
Count how many of the numbers are odd. If an odd number of them are odd, then their sum is odd. If an even number of them are odd, then their sum is even.
What is the sum of the first 1500 consecutive odd numbers?
You can work this out by realizing that the sum of the first x odd numbers is equal to x2.Consider the following examples:The first three odd numbers: 1 + 3 + 5 = 9The first five odd numbers: 1 + 3 + 5 + 7 + 9 = 25The first ten odd numbers: 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100In each case, the number of odds you're adding together is the square root of their sum. This means that the first 1500 consecutive odd numbers have a sum of 15002, which equals 2250000, or two and a quarter million.
What tree consecutive odd numbers have the sum of 51?
The numbers are 15, 17, and 19.
What are the 9 odd numbers whose sum is 50 from 1 to 50?
To find the 9 odd numbers whose sum is 50 from 1 to 50, we can first calculate the sum of all odd numbers from 1 to 50, which is (50^2)/2 = 625. Next, we subtract the sum of the first 9 odd numbers (1+3+5+7+9+11+13+15+17 = 81) from the total sum, resulting in 625 - 81 = 544. Therefore, the 9 odd numbers whose sum is 50 from 1 to 50 are 19, 21, 23, 25, 27, 29, 31, 33, and 36.
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.
How many pairs of odd numbers whose sum is 32?

What three consecvtive odd numbers have the the sum of 45?
They are: 13+15+17 = 45
What are three consecutive odd integers have a sum of 57?
The numbers are 17, 19, and 21.
What is an odd prime numbers less than 75 if the sum of the digit is 8?
17
What three consecutive odd numbershave a sum of 45?
The numbers are 13, 15 and 17.
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?
Well, honey, all you need to do is check the last digit of each number. If there's an odd number of odd digits, the sum is odd. If there's an even number of odd digits, the sum is even. So, in this case, 13 and 17 are odd, and 45 and 24 are even, which means the sum is odd without adding them all up. Easy peasy, lemon squeezy!
