Math question: What is the sum of all even numbers between 9942 and 200 (inclusive)?

To find the sum, we can use the formula for the sum of an arithmetic series: 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. The first even number after 9942 is 9944, and the last even number before 200 is 198. We can determine the number of terms by subtracting the first term from the last term, adding 2 (since both are even numbers), and dividing by 2, giving (198 - 9944 + 2)/2 = 9882/2 = 4941. Now we substitute the values into the formula: Sn = (4941/2)(9944 + 198) = 2470.5 * 10142 = 25,031,999. Thus, the sum of all even numbers between 9942 and 200 is 25,031,999.

Math Question: Find the sum of all even numbers between 9942 and 1, inclusive.

To solve this, we use the formula for the sum of an arithmetic series: Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. First, we identify the first term (a) as 9942 and the last term (l) as 2. We also need to find the number of terms (n). As it is an arithmetic series, we use the formula: n = (l - a)/d + 1, where d is the common difference. In this case, the common difference is -2 since we are subtracting 2 from each term to get the next even number. Using the formula, n = (2 - 9942)/(-2) + 1. Simplifying gives us n = 4970. Now substituting the values into the sum formula, we get Sn = (4970/2)(9942 + 2). Simplifying further, we have Sn = 2485 * 9944, giving us Sn = 24,709,840. Thus, the sum of all even numbers between 9942 and 1, inclusive, is 24,709,840.

Math question: What is the sum of the digits of the number 9942, multiplied by the difference between the largest and smallest digit?

The sum of the digits in 9942 is 9 + 9 + 4 + 2 = 24. The largest digit is 9, and the smallest digit is 2, so the difference is 9 - 2 = 7. Thus, the final answer is 24 multiplied by 7, which equals 168.
