Statement 1: The coefficient of `t^49` in the expression `(t + 1) (t + 2) (t + 3) ,… (t+ 50)` is equal to 1075. Statement-2 The value of `sum_(k=1)^(2n) k=n(2n+1)`.

if in a series t_(n)=(n+1)/((n+2)!) then sum_(n=0)^(10)t_(n) equal to

The fifth term of the sequence for which t_1= 1, t_2 = 2 and t_(n + 2) = t_n + t_(n + 1) is

If n^(th) term (T_(n)) of the sequece is given by the relation T_(n+1)=T_(n)+2^(n),(n epsilonN) and T_(1)=3 , then the value of sum_(r=1)^(oo)1/(T_(r)-1) equals

If sum _(r =1) ^(n ) T _(r) = (n +1) ( n +2) ( n +3) then find sum _( r =1) ^(n) (1)/(T _(r))
