Math Question: Find the smallest prime number larger than 1903 that leaves a remainder of 1 when divided by 3, 5, and 7.

To find the smallest prime number larger than 1903 (which is 1907), we can use the Chinese Remainder Theorem to determine the number that satisfies the given conditions. We start by taking the value 1 and consider its remainders when divided by 3, 5, and 7. We get 1, 1, and 1 respectively. By applying the Chinese Remainder Theorem, we find that the next number that shares these remainders is obtained by adding the product of these moduli (3*5*7 = 105) to 1. Hence, the smallest prime number larger than 1903 that satisfies the conditions is 1907 + 105 = 2012. In summary, the smallest prime number larger than 1903 that leaves a remainder of 1 when divided by 3, 5, and 7 is 2012.

Math question: Find the sum of multiples of 3 and 7 between 1903 and 200. Explanation: To find the multiples of 3 and 7, we first need to determine the highest multiple less than 1903 by dividing it by 3 and 7. By dividing 1903 by 3, we get 634.33, so the highest multiple of 3 less than 1903 is 633. We can do the same for 7, getting 271.85, indicating that the highest multiple of 7 less than 1903 is 271. Next, we calculate the lowest multiple greater than 200 by using the same division method. By dividing 200 by 3, we get 66.66, so the lowest multiple of 3 greater than 200 is 67. Similarly, dividing 200 by 7 results in 28.57, indicating the lowest multiple of 7 greater than 200 is 29. Now, we can determine the number of multiples between 633 and 67 for 3 (633 - 67)/3 + 1 = 189. This is derived from the formula (Last multiple - First multiple)/Common difference + 1. Similarly, for 7, we have (271 - 29)/7 + 1 = 37 multiples. Adding these two together, we have 189 + 37 = 226 multiples between 1903 and 200.

There are a total of 226 multiples of either 3 or 7 between the numbers 1903 and 200 (inclusive).

Math Question: What is the sum of the first 50 even numbers greater than 1903?

To find the sum of the first 50 even numbers greater than 1903, we can determine the pattern and apply a formula. The first even number greater than 1903 is 1904, and it increases by 2 each time. Therefore, the sum can be calculated as follows: Sum = n/2 * (first term + last term) = 50/2 * (1904 + (1904 + (50-1)*2)) = 25 * (1904 + 2048) = 25 * 3952 = 98,800 Hence, the sum of the first 50 even numbers greater than 1903 is 98,800, derived using the formula for the sum of an arithmetic series.
