What is the sum of all odd numbers between 1000 and 8000, excluding the number 7231?

To find the sum, we need to calculate the sum of the odd numbers in the given range and then subtract 7231 from it. The formula to find the sum of consecutive odd numbers is (n/2)(first odd number + last odd number), where n is the number of terms. First, we need to find the number of odd terms between 1000 and 8000. The first odd number is 1001, and the last odd number is 7999. The number of terms (n) is given by (last odd number - first odd number)/2 + 1 = (7999-1001)/2 + 1 = 3450. The sum of all odd numbers in the range is (3450/2)(1001 + 7999) = 1725 * 9000 = 15,525,000. Finally, we subtract 7231 from this sum to get the answer: 15,525,000 - 7231 = 15,517,769. So the answer is 15,517,769.

What is the sum of the digits in the number 7231?

To find the sum of the digits in the number 7231, we can add each digit individually. So, 7 + 2 + 3 + 1 = 13. Thus, the sum of the digits in 7231 is 13.

What is the sum of the digits in the number 7231?

To find the sum of the digits, we add each individual digit together. For the number 7231, the sum would be 7 + 2 + 3 + 1, resulting in a sum of 13.
