Explanation:

Step1: Verify Problem 24 pattern

Start with 0, add 0.5 each time:
$0 + 0.5 = 0.5$
$0.5 + 0.5 = 1$
$1 + 0.5 = 1.5$
$1.5 + 0.5 = 2$
$2 + 0.5 = 2.5$

Step2: Verify Problem 25 pattern

Start with 0, add 1 each time:
$0 + 1 = 1$
$1 + 1 = 2$
$2 + 1 = 3$
$3 + 1 = 4$
$4 + 1 = 5$

Step3: Create ordered pairs (24,25)

Match corresponding terms:
Third pair: $(1, 3)$
Fourth pair: $(1.5, 4)$
Fifth pair: $(2, 5)$
Sixth pair: $(2.5, 6)$

Step4: Define pair relationship

Let first value = $x$, second = $y$.
$y = \frac{x}{0.5} = 2x$

Answer:

1. $0, 0.5, 1, 1.5, 2, 2.5$
2. $0, 1, 2, 3, 4, 5$
3. $(1, 3), (1.5, 4), (2, 5), (2.5, 6)$
4. The second number in each ordered pair is twice the first number, or $y=2x$ where $x$ is the first value and $y$ is the second value.
