Find a recursive formula for the sequence n=1,2,3,... a_{n}=\frac{1}{n},
A. (ii)
B. (iii)
C. (i)
D. None of the other choices is correct
(i) a_{1}=1,a_{n+1}=a_{n}+\frac{1}{n+1} (n=1,2,3,...)
Next
(ii)(n=1,2,3,...)a_{1}=1,a_{n+1}=\frac{1}{a_{-}+1}
(ii) a_{1}=1, a_{n+1}=\frac{a_{n}}{a_{n}+1} (n=1,2,3,...)
