WebThe nth term of an AP is (7 - 4n). Find its common difference. Solution Given the nth term is 7 - 4n an= 7−4n Put n = 1, a1= 7−4×1 =7−4 =3 Put n = 2, a2= 7−4×2 =7−8 =−1 Common difference d=a2−a1 = −1−3= −4 So common difference of the AP is -4 Suggest Corrections 51 Similar questions Q. The nth term of an AP is (7 − 4n). Find its common difference. 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 ...
