1.选择题(共6题)

1.已知S1=x,S2=3S1﹣2,S3=3S2﹣2,S4=3S3﹣2,…,S2017=3S2016﹣2,则S3用含x的代数式表示为S3={#blank#}1{#/blank#};S2017={#blank#}2{#/blank#}.(结果用含x的代数式表示).
2.已知S1=x,S2=3S1﹣2,S3=3S2﹣2,S4=3S3﹣2,…,S2017=3S2016﹣2,则S3用含x的代数式表示为S3={#blank#}1{#/blank#};S2017={#blank#}2{#/blank#}.(结果用含x的代数式表示).
3.有这么一个数字游戏:

第一步:取一个自然数n1=5,计算n12+1得a1

第二步:算出a1的各位数字之和,得n2,计算n22+1得a2

第三步:算出a2的各位数字之和,得n3,再计算n32+1得a3,….

依此类推,则a2016={#blank#}1{#/blank#}.

4.观察下列各数:﹣ {#mathml#}12{#/mathml#} , {#mathml#}23{#/mathml#} ,﹣ {#mathml#}34{#/mathml#} , {#mathml#}45{#/mathml#} ,﹣ {#mathml#}56{#/mathml#} ,…,根据它们的排列规律写出第2015个数为{#blank#}1{#/blank#}.
5.已知整数a1,a2,a3,a4,…满足下列条件:a1=0,a2=﹣|a1+1|,a3=﹣|a2+2|,a4=﹣|a3+3|,…,依此类推,则a2016的值为{#blank#}1{#/blank#}.
6.a是不为1的有理数,我们把 {#mathml#}11a{#/mathml#} 称为a的差倒数.如:2的差倒数是 {#mathml#}112{#/mathml#} =﹣1,﹣1的差倒数是 {#mathml#}11(1){#/mathml#} = {#mathml#}12{#/mathml#} .已知a1=﹣ {#mathml#}13{#/mathml#} ,a2是a1的差倒数,a3是a2的差倒数,a4是a3的差倒数,…,依此类推,则a2015={#blank#}1{#/blank#}.
