GENERAL FORMULA for the Sum (Series) of an Arithmetic Sequence: The sum of N consecutive terms of an arithmetic sequence is one half the product of N (number of terms) times the sum first and last term. A0 + A1 + A2 + A3 +…+ AN-2 + AN-1 = Alternative Formula: a1 + a2 + a3 +…+ an-1 + an = Find the given sum for the arithmetic sequence:

If a1 is the first term of an arithmetic sequence, an the nth term, d is the common difference, a formula for finding the value of the nth term of an arithmetic sequence is: an = a1 + (n – 1)d. The formula for the nth term of an arithmetic sequence may be used to find any term of the sequence.

Introduce the explicit formula un = u1 + (n – 1)d, where un is any term of a sequence, n is the term number, u1 is the first term, and d is the common difference. (You may wish to explain that this formula is explicit because finding a given term does not require knowing the previous term.)
