The correct sigma notation for an arithmetic sequence is:

$$\sum_{n=1}^n\left(5-11n\right)$$

$$S_n=n\left(\frac{a_1+a_n}{2}\right)$$

$$S_n=a_1\left(\frac{1-r^n}{1-r}\right)$$

$$\sum_{n=1}^n50\left(0.75\right)^{\left(n-1\right)}$$

A divergent series means that...

the sum is closing in on a number

An arithmetic sequence...select all that apply....

uses $$a_n\ =\ a_1\ +\ \left(n\ -\ 1\right)\ d$$

uses $$a_n\ =\ a_1\ r\ ^{\left(n-1\right)}$$

uses $$a_1\ \left(\frac{1\ -\ r\ ^n}{1\ -\ r}\right)$$

An geometric sequence...select all that apply....

uses $$a_n\ =\ a_1\ r\ ^{\left(n-1\right)}$$

uses $$a_1\ \left(\frac{1\ -\ r\ ^n}{1\ -\ r}\right)$$

uses $$a_n\ =\ a_1\ +\ \left(n\ -\ 1\right)\ d$$
