I have a input and output machine . The input number is 5 and the output number 4. the second input number is 10 and the output is 5. I am having a hard time finding the operation. Can some please help thanks

how about

output = (1/5) x input + 3

9++17=80

To find the operation that relates the input and output numbers, we need to analyze the pattern between them in the given examples.

In the first set, the input number 5 is transformed into the output number 4. In the second set, the input number 10 is transformed into the output number 5.

By observing these examples, we can determine that the output number is calculated by subtracting 1 from the input number.

So, to find the operation, you need to subtract 1 from the input number.

For example, if the input number is 15, the output would be 14; if the input is 20, the output would be 19, and so on.

In summary, the operation is to subtract 1 from the input number to obtain the output number.
