S n Sum of n terms. Is also called general term of arithmetic sequence. An 35 n 37.
So the solution to finding the missing term is Example 2.
D Common difference. If the initial term of an arithmetic progression is and the common difference of successive members is d then the nth. The main purpose of this calculator is to find expression for the n th term of a given sequence. Use the general formula to generate terms of the sequence and write down the known variables.
