The first four sequences are shown below 9,5,1,-3 which of the following functions best defines this sequence

Arithmetic sequence.

Step-by-step explanation:

We have been given 9,5,1 and -3

We need to check what kind of sequence is this.

d is common difference we will check difference of consecutive terms.

We can see the difference between all the terms are same that is -4

So, this is an arithmetic sequence.

Arithmetic sequence is the sequence in which the difference between consecutive terms are same.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

the answer would be c:   ax + b = ax + c
