数列｛an｝中,满足a1=1,an+1=an+n,求｛an｝.不懂得不要乱说

已知数列{an}中满足(An+1-An)(An+1+An)=16,且a1=1,an 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 已知数列{an}满足a1=1 an+1=an/(3an+1) 则球an 数列｛an｝中,满足a1=1,an+1=an+n,求｛an｝.不懂得不要乱说 数列{an}满足a1=1 an+1=2n+1an/an+2n 已知数列{an}满足an+1=an+n,a1等于1,则an=? 数列｛an｝满足a1=1,且an=an-1+3n-2,求an 数列an满足a1=2,an+1=4an+9,则an=? 已知数列{an}满足an+1=2an+3.5^n,a1=6.求an 数列an满足a1=2,an+1=an²求an 数列an满足a1=2,an+1=an²求an 数列[An]满足An+1-An+3=0,且A1=-5.求An. 数列{an}中,a1=-60,an+1=an+3,若数列{bn}满足bn=|an|,求数列{bn}前30项和 数列an中,a1=3,an+1=an/2an+1,则an=? 已知数列{an}中a1=1,且满足an+an-1不等于0,Sn=1/6*(an+1)(an+2).(1)求通项an,并说明{an}是什么数列(2)求数列{an}的前n项和Sn 在数列an中,a1=1,且满足a（n+1）=3an +2n,求an 已知数列an满足 a1=1/2,an+1=3an/an+3求证1/an为等差数列已知数列an满足 a1=1/2,an+1=3an/an+3求证1/an为等差数列 数列an满足a1=1/2,a1+a2+a3……an=n^2an,则an
