To find the sum of the first 27 odd numbers, we can use the formula for the sum of an arithmetic series: Sn = n^2, where n is the number of terms. In this case, n = 27, so the sum is 27^2 = 729. Therefore, the sum of the first 27 odd numbers is 729.

What are the 9 odd numbers whose sum is 50 from 1 to 50?

To find the 9 odd numbers whose sum is 50 from 1 to 50, we can first calculate the sum of all odd numbers from 1 to 50, which is (50^2)/2 = 625. Next, we subtract the sum of the first 9 odd numbers (1+3+5+7+9+11+13+15+17 = 81) from the total sum, resulting in 625 - 81 = 544. Therefore, the 9 odd numbers whose sum is 50 from 1 to 50 are 19, 21, 23, 25, 27, 29, 31, 33, and 36.

What is the difference between the sum of all even numbers and odd numbers from 25 to 100?

The sum of the even numbers is (26 + 28 + ... + 100); The sum of the odd numbers is (25 + 27 + ... + 99) Their difference is: (26 + 28 + ... + 100) - (25 + 27 + ... + 99) = (26 - 25) + (28 - 27) + ... + (100 - 99) = 1 + 1 + ... + 1 There are (100 - 26) ÷ 2 + 1 = 38 terms above which are all 1; their sum is 38 x 1 = 38. So the difference of the sum of all even numbers and all odd numbers 25-100 is 38.

There is no solution. You could do it if the numbers were odd: 25 and 27 are consecutive odd numbers that equal 52.
