" 1.The sequence "{(n)/(n+1)}" is "

Find the sixth term of the sequence a_(n) =(n)/(n+1) ?

IF the nth terms of the sequence {u_(n)} is u_(n) = (-1)^(n-1).2^(-n) , find the corresponding series up to first five terms.

Find the 50th term of the sequence 1/n, (n+1)/(n), (2n+1)/(n),,……..

The sequence where a_(n)=(1)/(n+1)+(1)/(n+2)+(1)/(n+3)+......+(1)/(n+n) is

Write the first three terms of the sequence a_(n)=(-1)^(n-1) 5^(n+1)

Consider the sequence a _(n+1) = (1)/( 1 - a _(n)) , nge 1 Given that a _(1) = (1)/(2) find sum of first 100 terms of this sequence

COnsider the sequence (a_(n))n>=1, such that sum_(k=1)^(n)a_(k)=(3n^(2)+9n)/(2)AA n>=1. If lim_(n rarr oo)(1)/(na_(n))sum_(k=1)^(n)a_(k)=(p)/(q) (where p and q are coprime),then (p+q) is equal to
