数列{an}满足a1=1/2,a(n+1)=an^2+an(n∈N*),则m=1/(a1+1)+1/(a2+1)+...+1/(a2013+1)的整数部分是()A0 B1 C2 D3
1/a(n+1)=1/(an^2+an)=1/an-1/(an+1)
1/(an+1)= 1/an-1/a(n+1)
1/(a1+1)+1/(a2+1)+...+1/(a2013+1)=(1/a1-1/a2)+(1/a2-1/a3)+...+(1/a2013-1/a2014)
=1/a1 - 1/a2014=2-1/a2014
因为a(n+1)=an^2 +an
所以a(n+1) -an=an^2 >0
所以{an}是递增数列,
而a2=3/4 a3=21/16
当n>3时,an>a3=21/16
所以0
数列{an}满足a1=2,a(n+1)=2an+n+2,求an
