Explicit formula is useful to find any term of the sequence, without knowing the previous term. The explicit formula for the arithmetic sequence is an = a + (n - 1)d, and any term can be computed by substituting the n value for the term.
The formula an = a + ( n – 1 ) d is used to get the general term (or) nth term of an arithmetic progression (AP) whose first term is a, and the common difference is d. For example, we have the sequence 5, 8, 11, 14, 17, 20, 23, and 26....
