Question

Which function describes the arithmetic sequence shown -5,-7,-9,-11,-13

Answer 1

Answer:

$n(x)=x-2$

Step-by-step explanation:

You can notice that between each of the arithmetic sequence there is a addition of 2. So we know that to add a 2 to get the next value. We can write it as n(x) where n is a function where x is the number:

• n is the function and x repersent the number which is given

• We can write this function as: $n(x)=x-2$

• So if we input x = -5 we will get -7. If we input -11 we get -13.
