n/3 + 27
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.
The two equal numbers that have a sum of 54 are 27 and 27. When you add these two numbers together, you get 54. This is because the sum of two equal numbers will always be double the value of one of the numbers. In this case, 27 + 27 = 54.
let the number be n, then the sum of the number and 2 is n+2
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
