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. Concept: nth Term of an AP WebNov 25, 2024 · Given d = – 4 and a 7 = 4. We know that nth term of A.P. is. a n = a + (n – 1)d. a 7 = a + (7 – 1)d [n = 7] 4 = a + 6(– 4) ∴ a = 4 + 24 = 28 . ...
