“Private tutoring and its impact on students' academic achievement, formal schooling, and educational inequality in Korea.” Unpublished doctoral thesis. We can calculate the sum of this series, again by using the formula. When we sum a finite number of terms in an arithmetic sequence, we get a finite arithmetic series. In each of these sequences, the difference between consecutive terms is constant, and so the sequence is arithmetic. The difference between consecutive terms, an an 1, is d, the common difference, for n greater than or equal to two. Again, this is reiterated using a flowchart that explains the steps involved and the decisions to choose the correct formula to find the sum of first n terms in an arithmetic series. Now, this means we know the terms of the series. An arithmetic sequence is a sequence where the difference between consecutive terms is always the same. Tutors, instructors, experts, educators, and other professionals on the platform are independent contractors, who use their own styles, methods, and materials and create their own lesson plans based upon their experience, professional judgment, and the learners with whom they engage. Lastly, the sum of natural numbers and the sum of arithmetic series are explained for first n terms. Varsity Tutors connects learners with a variety of experts and professionals.
