Question: What is the sum of all odd numbers from 1 to 9938 inclusive?

To find the answer, we can use the formula for the sum of an arithmetic series: S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term. Here, a = 1, l = 9938, and we need to find the number of terms. As the sequence consists of odd numbers, the last term is odd as well. The formula for the nth odd number is 2n - 1, so we can solve 2n - 1 = 9938 to find n. Simplifying, we get n = (9938 + 1)/2 = 4970. Now we can substitute the values into the sum formula: S = (4970/2)(1 + 9938) = 24,700,070. Thus, the sum of all odd numbers from 1 to 9938 inclusive is 24,700,070.

What is the smallest prime number that can evenly divide the number 9938?

The smallest prime number that can evenly divide 9938 is 2. The prime factorization of 9938 is 2 × 4969, where both factors are prime numbers.

Math Question: If 9938 is divided by 2, multiplied by 7, and then subtracted by 1786, what is the result?

To solve the given expression: 9938 / 2 = 4969 4969 * 7 = 34783 34783 - 1786 = 32997 Therefore, when 9938 is divided by 2, multiplied by 7, and then subtracted by 1786, the result is 32997.
