Find the Sum of the First n Terms of an Arithmetic Sequence As with the general sequences, it is often useful to find the sum of an arithmetic

Arithmetic Sequences If the terms of a sequence differ by a constant, we say the sequence is arithmetic If the initial term of the sequence is a a

arithmetic sequence Explanation This formula tells us that, guven an arithmetic sequence, we can find the common difference d by subtracting any term from the next For example,

arithmetic sequence 2,4,6,8,10… is an arithmetic sequence with the common difference 2 If the first term of an arithmetic sequence
