Question

below is the table of values of a function. write the output when the input is n.
input output
1 4
2 8
5 20
n yellow box

Explanation:

Step1: Analyze the pattern

Check the relationship between input and output. For input 1, output is 4 ($1\times4 = 4$); for input 2, output is 8 ($2\times4 = 8$); for input 5, output is 20 ($5\times4 = 20$). So the pattern is output = input $\times4$.

Step2: Apply the pattern to input \( n \)

Using the pattern, when input is \( n \), output is \( 4\times n = 4n \).

Answer:

The output when the input is \( n \) is \( 4n \).
