Answer:

-84 would be next in the sequence.

Explanation:

The formula is x - 17.

-16 - 17 = -33

-33 - 17 = -50

-50 - 17 = -67

-67 - 17 = -84

-84 - 17 = -101 and so on...

The recursive formula for the sequence -16, -33, -50, -67, .... is f(n) = f(n - 1) - 17, f(1) = -16

Finding the recursive formula for the sequence

From the question, we have the following parameters that can be used in our computation:

-16, -33, -50, -67, ....

In the above sequence, we can see that -17 is added to the previous term to get the new term

This means that

First term, a = -16

Common difference, d = -17

The recursive formula for the sequence is then represented as

f(n) = f(n - 1) - 17, f(1) = -16
