Math Question: What is the sum of all positive multiples of 7 and 9 between 108 and 200, inclusive?

To find the sum of all positive multiples of 7 and 9, we need to identify the multiples of both numbers within the given range. Multiples of 7: 112, 119, 126, ..., 196 Multiples of 9: 108, 117, 126, ..., 198 Notice that 126 appears in both lists, so we must include it only once. Adding up all the multiples of 7 gives us: 112 + 119 + 126 + ... + 196 = 7(16 + 17 + 18 + ... + 28) Using the formula for the sum of an arithmetic series, where n is the number of terms and a_1 is the first term, the sum becomes: 7[(28-16)(16+28)/2] = 7(12)(44) = 3696 Adding up all the multiples of 9 gives us: 108 + 117 + 126 + ... + 198 = 9(12 + 13 + 14 + ... + 22) Applying the same formula, the sum is: 9[(22-12)(12+22)/2] = 9(10)(34) = 3060 Finally, to find the sum of all common multiples, we subtract the overlap: 3696 + 3060 - 126 = 6730 Therefore, the sum of all positive multiples of 7 and 9 between 108 and 200 is 6730.

Question: What is the sum of all even numbers from 2 to 108, inclusive?

To find the sum, we can 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. The first even term is 2, and to find the last even term, we need to figure out how many even numbers are between 2 and 108. The last even term can be found by subtracting 2 from 108 and then dividing by 2 (since we have alternating even and odd numbers). (108 - 2) / 2 = 53. Thus, the last even term is 106. Applying the formula, Sn = (53/2)(2 + 106) = 53 * 54 = 2862. Therefore, the sum of all even numbers from 2 to 108 is 2862.

Math Question: What is the sum of all natural numbers from 1 to 108?

To find the sum of a series, we can use the formula Sn = n/2 × (a + l), where Sn represents the sum of the series, a denotes the first term, l represents the last term, and n is the number of terms. In this case, a = 1, l = 108, and n = 108. Substituting these values into the formula, we have Sn = 108/2 × (1 + 108) = 54 × 109 = 5,886. Therefore, the sum of natural numbers from 1 to 108 is 5,886.
