What is the cumulative sum of the integers between 1 and 10, inclusive?
To find the cumulative sum of the integers between 1 and 10, you can use a mathematical formula or perform the calculation manually.
The mathematical formula for the sum of an arithmetic sequence is given by:
Sum = (n/2) * (first term + last term)
In this case, the first term is 1 and the last term is 10. The number of terms, n, can be found by subtracting the first term from the last term and adding 1.
n = 10 - 1 + 1 = 10
Now we can substitute these values into the formula:
Sum = (10/2) * (1 + 10) = 5 * 11 = 55
Therefore, the cumulative sum of the integers between 1 and 10, inclusive, is 55.
