Question

figure out the rule to complete the table:
in: -19, -17, -14, -5, blank, 0
out: -8, -6, -3, 6, 9, 11

Explanation:

Step1: Find the relationship rule

Test: $-19 + 11 = -8$, $-17 + 11 = -6$, $-14 + 11 = -3$, $-5 + 11 = 6$, $0 + 11 = 11$. The rule is: $\text{Out} = \text{In} + 11$

Step2: Solve for missing In value

Rearrange rule: $\text{In} = \text{Out} - 11$. Substitute Out=9:
$\text{In} = 9 - 11$

Answer:

$-2$
