WebWhat is an arithmetic Sequence? An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed number to the previous term. It is represented by the formula a_n = a_1 + (n-1)d, where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and d is the common difference, which is obtained by ... WebJul 7, 2024 · An arithmetic sequence is a sequence where the difference d between successive terms is constant. … An arithmetic series is the sum of the terms of an arithmetic sequence. The nth partial sum of an arithmetic sequence can be calculated using the first and last terms as follows: Sn=n(a1+an)2. WebVideo Transcript.
