### Example 1

Describe the sequence

3.1, 3.14, 3.141, 3.1415, 3.14159, ...

What is the general term *a _{n}*?

### Example 2

Evaluate the first 4 terms of the sequence, starting with *n* = 1.

### Example 3

Evaluate the first 4 terms of the sequence, starting with *n* = 1.

*a _{n}* = 2

*n*+ 1

### Example 4
