1.	Let an, nϵN is an A.P. with common difference ′d′ and whose all terms are non-zero. If n approaches infinity, then the sum 1a1a2+1a2a3+...+1anan+1 will approach
Answer» Let $a_{n}, n ϵ N$ is an A.P. with common difference $^{'} d^{'}$ and whose all terms are non-zero. If $n$ approaches infinity, then the sum $\frac{1}{a_{1} a_{2}} + \frac{1}{a_{2} a_{3}} + . . . + \frac{1}{a_{n} a_{n + 1}}$ will approach
