Question: how to find the formula for the nth term calculator?
Answer: For an arithmetic sequence, the nth term is calculated using the formula s + d x (n - 1). So the 5-th term of a sequence starting with 1 and with a difference (step) of 2, will be: 1 + 2 x (5 - 1) = 1 + 2 x 4 = 9. For a geometric sequence, the nth term is calculated using the formula s x s(n - 1).
