Math question: What is the sum of all even numbers between 1906 and 2000, excluding 2000?

To find the sum of all even numbers between 1906 and 2000 (excluding 2000), we can use the formula for the sum of an arithmetic series. We first identify the first term as 1906 and the last term as 1998 (since we are excluding 2000). The common difference is 2 since we are dealing with even numbers. The formula to find the sum of an arithmetic series is given by: S = (n/2)(first term + last term), where 'S' represents the sum and 'n' is the number of terms. To calculate, we find the number of terms: n = (last term - first term) / common difference + 1 = (1998 - 1906) / 2 + 1 = 98. Plugging these values into the formula: S = (98/2)(1906 + 1998) = 49(3904) = 191,296. Therefore, the sum of all even numbers between 1906 and 2000 (excluding 2000) is 191,296.

Math Question: What is the sum of all the odd numbers between 1906 and 2006, inclusive?

To find the sum of these odd numbers, we start with the first odd number, 1907, and add the subsequent odd numbers until we reach 2005. The difference between two successive odd numbers is always 2. So, we can represent the sum as follows: Sum = 1907 + (1907 + 2) + (1907 + 4) + ... + 2005 To find the number of terms in this sequence, we can use the formula for the nth term of an arithmetic sequence: nth term = first term + (n - 1) * common difference. In this case, the first term is 1907, the common difference is 2, and the last term is 2005. Solving the equation: 2005 = 1907 + (n - 1) * 2, n = (2005 - 1907 + 2)/2, n = 49. Hence, there are 49 odd numbers between 1906 and 2006, inclusive. Now, using the formula for the sum of an arithmetic series: Sum = (n/2)*(first term + last term), we can find the sum: Sum = (49/2)*(1907 + 2005) Sum = 24.5 * 3912 Sum = 95,724. Therefore, the sum of all odd numbers between 1906 and 2006, inclusive, is 95,724.

What is the sum of all the prime numbers between 1906 and 2000 inclusive?

To find the sum of prime numbers between 1906 and 2000, we need to identify the prime numbers within this range and add them up. Starting from 1906, we check if each number is prime by dividing it by numbers up to its square root. If a number is not divisible by any number except 1 and itself, it is prime. The prime numbers in the range are: 1907, 1913, 1931, 1933, 1949, 1951, 1973, 1979, 1987, 1993, 1997, and 1999. Summing them up, we get: 1907 + 1913 + 1931 + 1933 + 1949 + 1951 + 1973 + 1979 + 1987 + 1993 + 1997 + 1999 = 23732. Thus, the sum of all prime numbers between 1906 and 2000 inclusive is 23732.
