Arithmetic Sequences

arithmetic sequence If you're given the first few terms of an arithmetic sequence, you just need to identify the first term and the common difference (the number being added each

If the sequence has a common difference, it is arithmetic; if it has a common ratio, it is geometric We can therefore determine whether a sequence is arithmetic sequence The formula used to find the terms of an arithmetic sequence is a_n=a+d The subsequent terms of an arithmetic sequence can also be found by adding the
