Webn(2a+(n−1)d). Key Point The sum of the terms of an arithmetic progression gives an arithmetic series. If the starting value is a and the common difference is d then the sum of the first n terms is S n = 1 2 n(2a+(n−1)d). If we know the value of the last term ℓ instead of the common difference d then we can write the sum as S n = 1 2 n ...

WebLet the first term, common difference and the number of terms of an AP are a, d and n respectively. Given that, first term (a) = – 5 and last term (l) = 45 Sum of the terms of the AP = 120 ⇒ S n = 120 We know that, if last term of an AP is known, then sum of n terms of an AP is, So, the common difference is 10. in amy\\u0027s eyes james webb
