Math question: What is the sum of all the odd numbers between 1868 and 1?

To find the sum of odd numbers between 1868 and 1, we need to first determine the number of odd numbers within this range and then calculate their sum. The first odd number less than 1868 is 1867. To find the number of odd numbers between 1868 and 1, we subtract the first odd number from the last odd number: 1868 - 1 = 1867. Now, we need to find the sum of an arithmetic series. The formula for the sum of an arithmetic series is given by: Sn = (n/2)(a + l), where Sn represents the sum, n is the number of terms, a is the first term, and l is the last term. For our case, n = 1867/2 = 933.5. However, since we cannot have a fraction of terms, we round this value up to 934. The first term a = 1, and the last term l = 1867. Now we can substitute the values into the formula: Sn = (934/2)(1 + 1867) = 467 * 1868 = 871,076. Therefore, the sum of all the odd numbers between 1868 and 1 is 871,076.

Math question: What is the sum of the digits in the number 1868?

To find the sum of the digits in the number 1868, we add each digit individually. The digit 1 + digit 8 + digit 6 + digit 8 equals 23. Therefore, the sum of the digits in 1868 is 23.

Math question: What is the sum of all the even numbers between 1868 and 2000?

To find the sum of all even numbers between 1868 and 2000, we can use the formula for the sum of an arithmetic series. The first term, a, is 1870 (the next even number after 1868), the common difference, d, is 2, and the number of terms, n, can be calculated using the formula: n = (last term - first term) / common difference + 1. Substituting the values, we get n = (2000 - 1870) / 2 + 1 = 66. Now, applying the sum formula, S = n/2 * (first term + last term), we find S = 66/2 * (1870 + 2000) = 66 * 1935 = 127,410. Therefore, the sum of all even numbers between 1868 and 2000 is 127,410.
