WebHere, the first term is a = -5, and the common difference is, d = - (7/2) - (-5) = -2 - (-7/2) = ... = 3/2. The n th term of an arithmetic sequence is given by a n = a 1 + (n−1)d a n = -5 + (n - 1) (3/2) = -5+ (3/2)n - 3/2 = 3n/2 - 13/2 Answer: The n th term of the given arithmetic sequence is, a n = 3n/2 - 13/2.
