What is the pattern rule? (input and output) Input output 840 42 800 40 760 38 720 36 680 34

Step-by-step explanation:

The input/output rule or pattern rule is a set of commands that determines what the next input or output value will be. In this example:

input       output

840              42

800             40

760             38

720             36

680             34

pattern

input: The input decreases by 40 as we progress down the table. Subtract 40 from the previous input value to get the next input value

output: The output value is gotten by dividing the input by 20. for example; 840÷20 = 42, 800÷20 = 40 etc.
