Question: Find the sum of all even numbers between 1925 and 2000, inclusive.

To find the sum of the even numbers between 1925 and 2000, we first need to identify the range of numbers. The smallest even number in this range is 1926, and the largest is 2000. Next, we determine the number of even numbers from 1926 to 2000. We can divide the difference between the largest and smallest even numbers (2000 - 1926 = 74) by 2 and add 1, as the inclusive range requires counting both endpoints. There are (74/2) + 1 = 38 even numbers in this range. Now, we find the sum of these even numbers using the arithmetic series formula Sn = (n/2)(first term + last term). The first term is 1926, and the last term is 2000. Substituting these values, we get S38 = (38/2)(1926 + 2000) = 19(3926) = 74494. Therefore, the sum of all even numbers between 1925 and 2000 is 74494.

Math question: If the number 1925 is multiplied by a positive integer and then divided by 5, what is the sum of the resulting quotient and 100?

To find the result, we can write the equation: (1925 × a) ÷ 5 + 100 = b, where 'a' is the positive integer and 'b' is the sum. Solving for 'a', we get a = (5b - 500) ÷ 1925. Since 'a' must be a positive integer, substitute different values for 'b' (starting with 101) in the formula to find the first positive integer value for 'a' that satisfies the equation. For example, if we substitute b = 101, we find a = 1. Hence, the sum is b = 101. Feel free to continue this process to find subsequent answers with different values of 'b'.

Math question: What is the sum of all even numbers between 1925 and 1999 inclusive?

To find the sum, we need to determine the number of terms and calculate the average. First, identify the first and last even numbers in the given range: 1926 and 1998. To find the number of terms, subtract the first even number from the last, divide by 2 to account for the even sequence, and add 1: (1998 - 1926)/2 + 1 = 37. Now, compute the sum using the formula for the sum of an arithmetic series, where n represents the number of terms, a₁ is the first term, and l is the last term: sum = (n/2) * (a₁ + l) = (37/2) * (1926 + 1998) = 37 * 1962 = 72494. Hence, the sum of all even numbers between 1925 and 1999 is 72494.
