2. Find the common difference and the recursive formula. a. 22, 19, 16, 13, …

The common difference d is d = -3

The recursive formula is:

Step-by-step explanation:

We need to find the common difference and the recursive formula.

a. 22, 19, 16, 13, …

First we will find common difference

The formula of arithmetic sequence is:

where a_n is nth term, a_1 is 1st term and d is the difference

Looking at the sequence we get: a_1=22, a_2=19

Using these values we can find d, the common difference

So, the common difference d is d = -3

Now, we will find the recursive formula:

The recursive formula is of type:

We have found common difference d = -3

So, the recursive formula will be:

The recursive formula is:

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

-4, -2, 1, 4

domain = x values

range = y values
