Chapter 1.1, Problem 21PPSE

Solution

To Identify: The pattern by creating a table. The process column should be included.

The pattern is $\text{Output}=\text{Input}-1$

Given information:

Given the Graph:

  

Calculation:

Given the graph is as follows:

  

Make a table:

Input	Process Column	Output
$1$	$\left(1\right)-1$	$0$
$2$	$\left(2\right)-1$	$1$
$3$	$\left(3\right)-1$	$2$
$4$	$\left(4\right)-1$	$3$
$5$	$\left(5\right)-1$	$4$
$:$	$:$	$:$
$n$	$\left(n\right)-1$	$n-1$

The output is $1$ less than the input. Therefore, if the input is $n$ , the output is $n-1$ .

So, the pattern is $\text{Output}=\text{Input}-1$
