Question

find the rule and complete the table.
in out
1
2 10
60
65
16 80
19 95

Explanation:

Step1: Find the rule

Observe pairs like (16, 80) and (19, 95). We see that $80\div16 = 5$ and $95\div19=5$. The rule is Out = In $\times5$.

Step2: Calculate the first - missing value

When In = 1, using the rule Out = In $\times5$, we have Out = $1\times5=5$.

Step3: Calculate the second - missing value

When Out = 60, and using the rule Out = In $\times5$, then In = $60\div5 = 12$.

Step4: Calculate the third - missing value

When Out = 65, and using the rule Out = In $\times5$, then In = $65\div5=13$.

Answer:

In	Out
2	10
12	60
13	65
16	80
19	95
