Let `f(n)=log_1155 (n^3)` for all `n in N,` then find the value of `f(7)+f(11) + f(15).`

If   f(x ) = n/( n+1) , then find the value of f(n) + 1/f(n)

Let f:N to N for which f(m+n)=f(m)+f(n) forall m,n in N .If f(6)=18 then the value of f(2)*f(3) is

If f(n+1)=(2f(n)+1)/(2),n=1,2,3,... and f(1)=2 then find the value of f(101).

If f(n+1)=(1)/(2){f(n)+(9)/(f(n))},n in N and f(n)>0 for all n in N, then find lim_(n rarr oo)f(n)

Let f be a function from be set of positive integers to the set of real numbers i.e. f: N to R , such that f(1)+2f(2)+3f(3)+……+nf(n)=n(n+1)f(n) form ge2 , then find the value of f(1994).

If alpha and beta are the roots of the equation x^(2)-3x-15=0 and (n)=alpha^(n)+beta^(n) then find the value of (f(8)-3f(7)+f(6))/(2f(6))

If f(n + 1) = (2f(n) + 1)/2 , n = 1,2,3,....... and f(1) = 2, then find the value of f(101)
