The `r`th term of a series is given by `t_r=r/(1+r^2+r^4)`, then `lim(n->oo)sum_(r=1)^n(t_r)`

let the rth term of the series is given by tr=(r)/(1+r^(2)+r^(4)) then lim_(n rarr oo)sum_(r=1)^(n)t_(r) is equal to: ( A) (1)/(2)(B)1(C)2(D)(1)/(4)

The rth term of a series is given by t_(r)=(r)/(1+r^(2)+r_(n)^(4)), then lim(n rarr oo)sum_(r=1)^(n)(t_(r))

Let the rth term t_(r) of a series is given by t_(r)=r/(1+r^(2)+r^(4)) , the value of lim_(ntooo)sum_(r=1)^(n)t_(r) is

Let rth term of a series be given by T_(r)=(r)/(1-3r^(2)+r^(4)) then Lt_(n rarr oo)sum_(r=1)^(n)T_(r)=

The r^(th) term t_(r) of a series is given by t_(r)=(r)/(r^(4)+r^(2)+1) then lim_(n to oo) overset(n) underset(r=1) sum t_(r)=

Let the rth term, t_(r) , of a series is given by : t_(r) = (r)/(1+r^(2) + r^(4)) . "Then" lim_(n rarr oo) sum_(r = 1)^(n) t_(r) equals :

Let r^(th) term t _(r) of a series if given by t _(c ) = (r )/(1+r^(2) + r^(4)) . Then lim _(n to oo) sum _(r =1) ^(n) t _(r) is equal to :

If T_r=r(r^2-1), then find sum_(r=2)^oo1/Tdot

If T_r=r(r^2-1), then find sum_(r=2)^oo1/Tdot

If t_(r)=(r)/(4r^(4)+1), then sum_(r=1)^(oo)t_(r) is equal to
