Math question: What is the sum of all even numbers between 124 and 200 (inclusive)?

To find the sum of all even numbers between 124 and 200, we need to first identify all the even numbers within this range. Starting from 124, we have 124, 126, 128, 130...and so on, up to 200. Notice that the difference between each consecutive even number is always 2. To find the number of terms, we can use the formula: Number of Terms = (Last term - First term) / Common Difference + 1 In this case, the first term is 124, the last term is 200, and the common difference is 2. Substituting these values into the formula, we get: Number of Terms = (200 - 124) / 2 + 1 = (76) / 2 + 1 = 38 + 1 = 39 Next, to find the sum, we use the formula for the sum of an arithmetic series: Sum = (Number of Terms / 2) * (First term + Last term) Plugging in the numbers from our problem, we have: Sum = (39 / 2) * (124 + 200) = 19.5 * 324 = 6354 Therefore, the sum of all even numbers between 124 and 200 is 6,354.

Math question: If the number 124 is multiplied by 3, divided by 6, and then added to the square root of 124, what is the result?

To solve this, we start with multiplying 124 by 3, giving us 372. Then we divide 372 by 6, which yields 62. Next, we find the square root of 124, which is approximately 11.1355. Now, we add 62 and 11.1355 together, resulting in 73.1355. Therefore, the final calculation is 124 × 3 ÷ 6 + √124 = 73.1355.

Math question: What is the sum of the first 62 positive even numbers, plus the first 62 positive odd numbers, minus the first 62 natural numbers?

To find the sum of the first 62 positive even numbers, we use the formula: even_sum = n(n+1), where n is the last even number. For 62 even numbers, the last even number is 62*2 = 124. Thus, the sum of the first 62 positive even numbers is even_sum = 62(62+1) = 3906. Similarly, to find the sum of the first 62 positive odd numbers, we use the formula: odd_sum = n^2, where n is the last odd number. Since the last odd number is 2*n - 1, for 62 odd numbers, the last odd number is 2*62 - 1 = 123. Hence, the sum of the first 62 positive odd numbers is odd_sum = 62^2 = 3844. Now, to find the sum of the first 62 natural numbers, we use the formula: natural_sum = n(n+1)/2, where n is the last natural number. For 62 natural numbers, n is 62, so the sum of the first 62 natural numbers is natural_sum = 62(62+1)/2 = 1953. Finally, we can compute the desired sum as even_sum + odd_sum - natural_sum = 3906 + 3844 - 1953 = 5797.
