The sum of the first n terms of an A P is 4n 2 2n Find the nth term of this A P - Given:The sum of first $n$ terms of an A.P. is $4n^{2} +2n$.To do:We have to find the $n^{th}$ term of the given A.P.Solution:$S_{n} =4n^{2} +...
is 24 and the sum of the 6^(th) and 10^(th) terms is 44. Find the first three terms of the A.P.相关知识点: 试题来源: 解析 Solutions: We know that, the nth term of the AP is;a_n = a + (n − 1) da_4 = a + (4 − 1) da_4 = a + 3dIn the same ...
(-1/2)=3+2= 5, whend =-1/2We know, the sum of nth term of AP is;Sn=n/2[2a+(n-1)dSo, when a = 1 and d=1/2T hen, the sum of first 16 terms are;S16=16/2[2+(16-1)1/2=8(2+15/2)=76And when a = 5 and d= -1/2T hen, the sum of first 16 terms are;...
