What is the sum 1 2 3 4 up to 50?
The sum of the numbers 1 through 50 can be found using the formula for the sum of an arithmetic series: [(n/2) * (first term + last term)], where n is the number of terms. In this case, n = 50 and the first term is 1 and the last term is 50. Plugging those values into the formula, the sum is 1275.
