WebWe know that an AP is a sequence where each term, except the first term, is obtained by adding a fixed number to its previous term. Here, the “fixed number” is called the “ common difference ” and is denoted by 'd' i.e., if the first term is a 1 , then: the second term is a 1 + d, the third term is a 1 + d + d = a 1 + 2d, and the fourth ... WebMar 18, 2024 · Where; a = first term for the given A.P. d = common difference of the given A.P. n = number of terms. 51 terms of an AP whose a 2 = 2 and a 4 = 8. We know that, a 2 = a + d. 2 = a + d …(2) Also, a 4 = a + 3d. 8 = a + 3d … (2) Subtracting (1) from (2), we have. 2d = 6. d = 3. Substituting d = 3 in (1), we get. 2 = a + 3. a = -1 WebWe know that the nth term of an AP is given by the formula a n = a + (n – 1) d. a 8 = 1 2 a 2 2 a 8 = a 2 2 (a + 7 d) = a + d 2 a + 14 d = a + d ∴ a = – 13 d. a 11 = 1 3 a 4 + 1 3 (a + 10 d) = … product for rule counting
