Let `f:N rarr R` be such that f(1)=1 and f(1)+2f(2)+3f(3)+…+nf(n)=n(n+1)f(n), for `n ge 2, " then " `/(2010f(2010))` is ……….. .

Let f : N rarr R be a function such that f(1) + 2f(2) + 3f(3) + ....+nf(n)= n(n+1) f(n) , for n ge 2 and f(1) = 1 then

Let f be a function from the set of positive integers to the set of real number such that f(1)=1 and sum_(r=1)^(n)rf(r)=n(n+1)f(n), forall n ge 2 the value of 2126 f(1063) is ………….. .

Let f:N rarr R be such that f(1)=1 and f(1)+2f(2)+3f(3)+nf(n) ,for all n in N,n>=2, where N is the set of natural numbers and R is the set of real numbers. Then the value of f(500) is

Let f:N rarr R be a function such that (ii) f(1)+2f(2)+3f(3)+.........+nf(n)=n(n+1)f(n)=n(n+1)f(n)AA n>=2 Then find f(2011)
