Question

Pls help! URGENT ONLY DO QUESTION 21 PLS

Answer 1

Answer:

y = x - 8

Step-by-step explanation:

There's no magic method to doing these, and problem 21 makes it harder to see a pattern by using inputs that are not consecutive integers (like problem 20 does)!

Looking at inputs 20 and 21, the outputs are 8 less than the inputs.  Check the other inputs and notice that the same pattern holds up.
