Arithmetic sequences
arithmetic sequence Arithmetic Progression · The formula for finding the n-th term of an AP is: · Where · a = First term · d = Common difference · n = number of terms · = nth term
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 If the first term of the sequence is a and the common difference is d, then the arithmetic sequence can be written as a, a+d, a+2d, a+3d, …, a+d, …
