In an ap the first term is - 4
WebFeb 13, 2024 · The first four terms of AP are 8,3,-2 and -7. Given : In an AP, a = 8 and d = -5 . To find : The first four terms of AP. Solution: We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the first four terms of AP) We know that : Nth term of an AP = a + (N-1) × d . Where, a = First ... WebSum of n AP terms = S n = n 2 [ 2 a + ( n − 1) d] Where a is first term of AP and d is difference between two consecutive terms of AP. Calculation: Given series is 2, 4, 6, 8, 10,....... a = 2 and d = 2 Let sum of n terms of AP is 210. Therefore, 210 = n 2 [ 2 × 2 + ( n − 1) 2] ⇒ n 2 + n - 210 = 0 ⇒ n 2 + 15n - 14n - 210 = 0

In order to find any term in an arithmetic sequence, replace n with the term and solve using the formula obtained for the n th term, hence, if the first term is required, n=1, and the term is a 1. In the case of the 2nd term, put n=2, and the term is a2, and so on.

WebMar 18, 2024 · Best answer Given that, a = 22, d = – 4 and Sn = 64 Let us consider the number of terms as n. For sum of terms in an A.P, we know that Sn = n 2 n 2 [2a + (n − 1)d] Where; a = first term for the given A.P. d = common difference of the given A.P. n = number of terms So, Sn = n 2 n 2 [2 (22) + (n − 1) (−4)] 64 = n 2 n 2 [2 (22) + (n − 1) (−4)]
