In an a.p. d 4 n 7 nth term 4 then a is
WebIn an AP, if d = –4, n = 7, an = 4, then a is (A) 6 (B) 7 (C) 20 (D) 28 Solution: (D) 28 Explanation: We know that nth term of an AP is a n = a + (n – 1)d where, a = first term a n is nth term d is the common difference According to the question, 4 = a + (7 – 1) (- 4) 4 = a – 24 a = 24 + 4 = 28 2. WebAn arithmetic progression or arithmetic sequence (AP) is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression …
