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 ... WebIn an AP, if the common difference (d) = –4, and the seventh term (a 7) is 4, then find the first term. Advertisement Remove all ads Solution n 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.
