Explanation:

Step1: Match sequence 24 and 25 values

Take the 3rd value from problem 24 ($1$) and problem 25 ($2$) to form the next ordered pair: $(1, 2)$

Step2: Match 4th values of both sequences

Take the 4th value from problem 24 ($1.5$) and problem 25 ($3$) to form the next ordered pair: $(1.5, 3)$

Step3: Match 5th values of both sequences

Take the 5th value from problem 24 ($2$) and problem 25 ($4$) to form the next ordered pair: $(2, 4)$

Step4: Match 6th values of both sequences

Take the 6th value from problem 24 ($2.5$) and problem 25 ($5$) to form the next ordered pair: $(2.5, 5)$

Step5: Identify the relationship

Check the ratio of the second number to the first number in each pair:
$\frac{0}{0}$ (undefined, initial pair), $\frac{1}{0.5}=2$, $\frac{2}{1}=2$, $\frac{3}{1.5}=2$, $\frac{4}{2}=2$, $\frac{5}{2.5}=2$.
The second number is twice the first number.

Answer:

Ordered pairs: $(1, 2), (1.5, 3), (2, 4), (2.5, 5)$
Relationship: The second number in each ordered pair is equal to twice the first number, or mathematically, if the first number is $x$ and the second is $y$, then $y=2x$.
