If `sum_(r=1)^n t_r=n/8(n+1)(n+2)(n+3),` then find `sum_(r=1)^n1/(t_r)dot`

If Sigma_(r=1)^(n) T_r=n/8(n+1)(n+2)(n+3) then find Sigma_(r=1)^(n) 1/T_r

If sum_(r=1)^(n)T_(r)=(n)/(8)(n+1)(n+2)(n+3)," find "sum_(r=1)^(n)(1)/(T_(r)) .

If sum_(r=1)^(n)T_(r)=n(2n^(2)+9n+13), then find the sum sum_(r=1)^(n)sqrt(T_(r))

If sum_(r=1)^(n)T_(r)=(3^(n)-1), then find the sum of sum_(r=1)^(n)(1)/(T_(r))

If sum_(r=1)^(n)T_(r)=(n(n+1)(n+2))/(6), then the value of sum_(r=1)^(oo)((1)/(T_(r))) is equal to

If sum_(i=1)^(n)Tr=(n(n+1)(n+3))/(3), then sum_(r=1)^(n)(2008)/(T_(r)) is (A) 2008(B) 3012(C) 4016(D) 8032

If sum_(r=1)^(n)t_(r)=(1)/(4)n(n+1)(n+2)(n+3) then value of (1)/(sum_(r=1)^(oo)((1)/(t_(r)))) is
