梁败程3432数列{an}满足a1=1,且对任意的正整数m,n都有am+n=am+an+mn,则1a1+1a2+…+1a2013+1a2014= - ----- -
堵炭非15717363820 ______ 令m=1,得an+1=a1+an+n=1+an+n,∴an+1-an=n+1,用叠加法:an=a1+(a2-a1)+…+(an-an-1)=1+2+…+n=,∴==2(),∴++…++=2(1-)=2(1-)=. 故答案为:.

梁败程3432等差数列{an}中,若an=m,am=n,证Sm+n= - (m+n) -
堵炭非15717363820 ______ {an}为等差数列 则:设an=a+nd,d为公差 ,a=a1-d.这是个常用的素公式. 则有: Sm=am+dm(m+1)/2=n Sn=an+dn(n+1)/2=m 解得: d=-(2m+2n)/mn a=(m^2+n^2+mn+m+n)/mn 所以: S(m+n) =(m+n)a+d(m+n)(m+n+1)/2 =-(m+n)

梁败程3432现有数列{an}满足:a1=1,且对任意的m,n∈N*都有:am+n=am+an+mn,则1a1+1a2+1a3+…+1a2014=( )A. -
堵炭非15717363820 ______ ∵数列{an}满足:a1=1, 且对任意的m,n∈N*都有:am+n=am+an+mn, ∴令m=1,得an+1=an+a1+n, ∴an+1-an=1+n, ∴an=a1+(a2-a1)+…+(an-an-1)=1+2+…+n= n(n+1) 2 . ∴ 1 an = 2 n(n+1) =2( 1 n ? 1 n+1 ), ∴ 1 a1 + 1 a2 + 1 a3 +…+ 1 a2014 =2(1- 1 2 + 1 2 ? 1 3 + 1 3 ? 1 4 +…+ 1 2014 ? 1 2015 )=2(1- 1 2015 )= 4028 2015 . 故选:D.

梁败程3432数列an满足a1=1,且对任意m,n都有am+n=am+an+mn,则1/a1+1/a2+...+1/a2010= -
堵炭非15717363820 ______ 令m=1 有a(n+1)=a(n)+a(1)+n=a(n)+n+1 a(n)=a(n-1)+n a(n-1)=a(n-2)+n-1 ... a(2)=a(1)+2 那么把式子左右分别相加,得到a(n)=a(1)+2+...+n=(n+1)n/2 1/a(1)+1/a(2)+...+1/a(2010) =2/(1*2)+2/(2*3)+...+2/(2010*2011) =2[1/(1*2)+1/(2*3)+...+1/(2010*2011)] =2[1/1-1/2+1/2-1/3+...+1/2010-1/2011] =2[1-1/2011] =4020/2011
