Question 295510: The sum S of a list of consecutive integers beginning with one can be determined by evaluating the formula S=n/2(n+1), where n is the number of integers in the list. Using this formula, determine the number of consecutive positive integers beginning with one that must be added together so that the sum is 703.

multiply all by 2

n - 37 = 0 or n + 38 = 0
n = 37 or n = -38
because the number of the integers can't be a negative number, so the number of the integers = 37
