WebLet's see why the formula works, because we get to use an interesting "trick" which is worth knowing. First, we will call the whole sum "S": S = a + (a + d) + ... + (a + (n−2)d) + (a + (n−1)d) Next, rewrite S in reverse order: S = (a + (n−1)d) + (a + (n−2)d) + ... + (a + d) + a Now add those two, term by term: Each term is the same! WebFormula to find the sum of first n terms of an AP is S_ {n} = \frac {n} {2} [2a + (n-1)d] S n = 2n[2a+(n−1)d] OR S_ {n} = \frac {n} {2} (a+l) S n = 2n (a+ l) where, a = first term, d= common difference, t n = n th term = a + (n-1)d Arithmetic Mean If a, b, c are in AP, then the Arithmetic mean of a and c is b i.e.
