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. Web2 S = ( a 1 + a n) + ( a 1 + a n) + ( a 1 + a n) + ( a 1 + a n) +... + ( a 1 + a n) 2 S = n ( a 1 + a n) S = n 2 ( a 1 + a n) Substitute an = a1 + ( n - 1) d to the above equation, we have S = n 2 { a 1 + [ a 1 + ( n − 1) d] } S = n 2 [ 2 a 1 + ( n − 1) d] Tags: Algebra Derivation of Formula Progression sequence series Arithmetic Progression WebLet n = 1, then a (1) = S (1) - S (0) and S (n) = (n+1)/ (n+10) that implies S (1) = 2/11,S (0) = 1/10 but S (0) = Sum of first 0 terms which is equal to zero ( S (0) = 0 ) and that is a contradiction. So the formula a (n) = S (n) -S (n-1) works only for n > 1. flashing ice cube turn off
