Formula of ap and gp
WebIf a,b and c are in AP and also in GP, then a=b=c 27. If a, b and c are in AP, then xa, xb and xc are in geometric progression. Class 11 Key Points, Important Questions & Practice Papers Hope these notes helped you in your schools exam preparation. WebTo do this, we just substitute our formula for ℓ into our formula for S n. From ℓ = a+(n−1)d, S n = 1 2 n(a+ℓ) we obtain S n = 1 2 n(a+a+(n− 1)d) = 1 2 n(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 ...
