Webn th term of an AP is T n =a+ (n−1)d For an AP with the first term as 'a' and common difference as 'd', the seventh term is a + 6d. According to the question, the common difference (d) is −4 and the seventh term (a 7) is 4. So, a + 6d will be ⇒ a + 6 (−4) = 4 ⇒ a = 28 Hence, the first term is 28.
