Quizplus · Accepted Answer

The even integers between 37 and 69 are 38, 40, 42, ..., 68. This is an arithmetic sequence with the first term a = 38, the last term l = 68, and the common difference d = 2. The number of terms n can be found using the formula n = (l - a)/d + 1 = (68 - 38)/2 + 1 = 16. The sum of an arithmetic sequence is given by S = n/2 * (a + l) = 16/2 * (38 + 68) = 8 * 106 = 848.
