It is clear that a(n)=2^(1-2^(-n)). In fact, for n=1 this produces 2^(1-1/2)=sqrt(2)=a1 and if it is true for a(n) then a(n+1) = sqrt (2 * 2^(1-2^(-n))) = sqrt(2^(2-2^(-n))) = 2^(1-2^(-(n+1))) (a) clearly 2^(1-2^(-n))<2<3 so the sequence is bounded by 3. Also a(n+1)/a(n) = 2^(1-2^(-n-1) - 1+2^(-n)) = 2^(1/2^n - 1/2^(n+1)) = 2^(1/2^(n+1)) >1 so the sequence is monotonically increasing. As it is monotonically increasing and has an upper bound it means it has a limin when n-> oo (b) 1-1/2^n -> 1 as n->oo so 2^(1-2^(-n)) -> 2 as n->oo
Answer:
A paragraph on the importance of knowledge and skills in storing salads properly.
Explanation:
Since salads are mostly raw vegetables, their taste is important. And to make them as fresh as possible, it is important to know how to properly store them. This knowledge on how to store them will ensure the taste is at its best and also not ruin the whole eating experience. The fresher the salads are, the tastier they are. So, to do that, one must store such salads on a container lined with damp-not soggy- paper towels, to keep the freshness. This will help retain the moisture but not wilt the vegetables, and keep them fresh and crunchy as they should be when served.
