What is the sum of the first 10 prime numbers greater than 66?

The first prime number greater than 66 is 67. The next prime number is 71, followed by 73, 79, 83, 89, 97, 101, 103, and 107. Adding these prime numbers together gives a sum of 940.

Math Question: What is the sum of all positive integers from 1 to 66, inclusive?

To find the sum, we can use the formula for the sum of an arithmetic series: Sn = (n/2)(first term + last term), where Sn represents the sum of n terms. For the given range, the first term is 1 and the last term is 66. Plugging these values into the formula, we can calculate Sn = (66/2)(1 + 66) = (33)(67) = 2211. Therefore, the sum of all positive integers from 1 to 66 is 2211.

Math question: What is the sum of all even numbers between 66 and 200, inclusive?

To find the sum of all even numbers between 66 and 200, we can first identify the first and last even numbers in this range. The first even number is 66, and the last even number is 200. We can observe that the numbers in this sequence form an arithmetic progression with a common difference of 2. Using the formula for the sum of an arithmetic sequence, Sn = (n/2)(a + l), where Sn represents the sum, n represents the number of terms, a represents the first term, and l represents the last term, we can calculate the sum of even numbers as: Sn = (n/2)(a + l) = (n/2)(66 + 200) = (n/2)(266) To determine the number of terms, n, we can subtract the first term (66) from the last term (200) and then divide the result by the common difference (2): n = (l - a)/d = (200 - 66)/2 = 134/2 = 67 Substituting n = 67 in our sum formula, we can find: Sn = (67/2)(266) = 67 × 133 = 8931 Therefore, the sum of all even numbers between 66 and 200 is 8931.
