Find the indicated term of each aithmetic sequence
28th term; 0,-4,-8,-12 过程最重要.不然看了答案也不会算.
28th term; 0,-4,-8,-12 过程最重要.不然看了答案也不会算.
规律为:(-4)*(n-1)
第28项为:(-4)*(28-1)=-108
再问: 题目是第7题:28th term:0,-4,-8,-12,...
再答: 你那是第7小题,对吧? 7.
再问: 对,希望可以发过程
再答: 第一项(-4)*(n-1)=(-4)*(1-1)=0 第二项(-4)*(n-1)=(-4)*(2-1)=-4 第三项(-4)*(n-1)=(-4)*(3-1)=-8 …… 第28项(-4)*(n-1)=(-4)*(28-1)=-108
再问: 规律一定是(-4)*(n-1)?还有这题呢?第九题:17th term;a的右下角有个1不知怎么打 a1=2.3;d=-2.3
再答: 17term 是负的。 奇数项为正,偶数项为负,第17项为2.3
第28项为:(-4)*(28-1)=-108
