Answer 3

To find the sum of the arithmetic series from 19 to 103 using the Gauss method (also known as the Gaussian sum formula), you need to follow these steps:

Step 1: Determine the first term (a) and the last term (l) in the series. a = 19 l = 103

Step 2: Find the number of terms (n) in the series. The formula for finding the number of terms in an arithmetic series is: n = ((l - a) / d) + 1, where d is the common difference between consecutive terms. In this case, the common difference (d) is 1. n = ((103 - 19) / 1) + 1 n = 85 + 1 n = 86

Step 3: Apply the Gauss method to find the sum (S) of the series: S = (n / 2) * (a + l)

Now, plug in the values: S = (86 / 2) * (19 + 103) S = 43 * 122 S = 5254

Therefore, the sum of the arithmetic series from 19 to 103 is 5254.
