Question

me ayudan a calcular la razón en matematicas.​

Answer 1

 

1a_{n}=1,2,3,4,5,...,n

 

2a_{n}=-1,-2,-3,-4,-5,...-n

 

3\displaystyle a_{n}=2,\cfrac{3}{2},\cfrac{4}{3},\cfrac{5}{4},...,\cfrac{n+1}{n}

 

4a_{n}=2,-4,8,-16,32,...,\left ( -1 \right )^{n-1}\cdot 2^{n}

 

5 \displaystyle a_{n}=\cfrac{n+2}{2n+1}

 

6a_{n}=\left ( -1 \right )^{n-1}\cdot 2^{n}

 

7\displaystyle 1,-1,\cfrac{1}{2},-\frac{1}{2},\frac{1}{3},-\frac{1}{3},...

 

8\displaystyle a_{n}=\cfrac{n}{n+1}
