Question: What is the sum of all even numbers from 4990 to 1?

To find the sum of all even numbers from 4990 to 1, we can use the arithmetic series formula. The first term (a) is 5000, the last term (l) is 2, and the common difference (d) is -2. By plugging these values into the formula, Sum = (n/2)(a + l), where n is the number of terms, we can calculate n using the formula n = (l - a)/d + 1. In this case, n = (2 - 5000)/(-2) + 1, which simplifies to n = 2500. Plugging this value of n into the sum formula, we have Sum = (2500/2)(5000 + 2), which simplifies to Sum = 1250(5002). The final answer is Sum = 6,252,500.

Question: What is the largest prime factor of the number 4990?

To find the largest prime factor of 4990, we can start by dividing it by the smallest prime number, 2. We get 2495. Continuing the process, we divide 2495 by 5 to yield 499. Upon dividing 499 by 499, we find that it is a prime number. Therefore, the largest prime factor of 4990 is 499.

Math question: What is the sum of the first 100 positive even numbers larger than 4990?

To find the sum, we begin by identifying the first even number larger than 4990, which is 4992. The next 99 consecutive even numbers can be obtained by adding 2 successively. We calculate the sum as follows: 4992 + (4992 + 2) + (4992 + 4) + ... + (4992 + 198). Using the arithmetic series formula where S = n/2 * (first term + last term), we have n = 100 (since we have 100 terms), first term = 4992, and last term = 4992 + 198 = 5190. Substituting these values, our formula becomes S = 100/2 * (4992 + 5190) = 100/2 * 10182 = 510900. Therefore, the sum of the first 100 positive even numbers larger than 4990 is 510900.
