Question: What is the sum of all odd numbers between 1 and 98, inclusive?

To find the sum of odd numbers between 1 and 98, we need to determine the number of odd numbers in that range and calculate their sum. The first odd number in this range is 1, and the last odd number is 97. We can use the formula to find the number of odd numbers in a sequence: (Last number - First number) / 2 + 1. Applying this formula, we get (97 - 1) / 2 + 1 = 49. Therefore, there are 49 odd numbers between 1 and 98. To find their sum, we can use the formula for the sum of an arithmetic series: Sum = (First number + Last number) / 2 * Number of terms. Substituting the values, we have (1 + 97) / 2 * 49 = 49 * 49 = 2401. Hence, the sum of all odd numbers between 1 and 98 is 2401.

Math question: What is the sum of the multiples of 7 from 98 to 200, inclusive?

To find the sum, we need to determine the number of multiples of 7 in this range and then add them up. The first multiple of 7 within the range is 98, and the last is 196. We can subtract 98 from 196, or divide (196-98) by 7 (which gives 14), then we add 1 (since we count inclusive). So, there are 15 multiples of 7 in this range. To find the sum, we can use the arithmetic series formula: 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. In this case, n = 15, a = 98, and l = 196. Plugging the values into the formula, we have S = (15/2)(98 + 196) = (15/2)(294) = 11025. Therefore, the sum of the multiples of 7 from 98 to 200 is 11025.

Math question: What is the sum of all numbers divisible by 7 but not divisible by 5 between 98 and 200 (inclusive)?

To find the sum, we first determine the smallest number divisible by 7 but not divisible by 5 within the given range, which is 105. Next, we identify the largest number fulfilling this condition, which is 196. Now we need to find the number of terms in the series by using the formula (last term - first term) / common difference + 1, where the common difference is 7. Substituting the values, we get (196 - 105) / 7 + 1 = 13. Therefore, the sum of this arithmetic series is calculated using the formula S = n/2 * (first term + last term), where n is the number of terms. Substituting the values, we have 13/2 * (105 + 196) = 13/2 * 301 = 3913. Hence, the sum of all the numbers between 98 and 200 that are divisible by 7 but not divisible by 5 is 3913.
