1. First understand the definition of Gaussian algorithm, multiply the first term and the last term by the number of terms and then divide by 2 to calculate the result of "1+2+3+4+5+(n-1)+n". Such an algorithm is called Gaussian algorithm.

2. Then use this algorithm to calculate17+23+29+…+191+197, multiply the first and last terms by the number of terms and divide by 2.

3. The final result is (17+197) × 312 = 3317.
