9. four coworkers created a sequence of six numbers as part of a training exercise. the table below shows the sequence each coworker created. which coworkers sequence changes by the same amount from one number to the next?

9. four coworkers created a sequence of six numbers as part of a training exercise. the table below shows the sequence each coworker created. which coworkers sequence changes by the same amount from one number to the next?

Answer

Explanation:

Step1: Analyze Mark's sequence

Calculate the differences: (30 - 15=15), (60 - 30 = 30), (120-60 = 60). The differences are not the same.

Step2: Analyze Sam's sequence

Calculate the differences: (8 - 4=4), (12 - 8 = 4), (16-12 = 4), (20 - 16=4), (24-20 = 4). The differences are all (4).

Step3: Analyze Jess's sequence

Calculate the differences: (11 - 9=2), (15 - 11 = 4), (21-15 = 6). The differences are not the same.

Step4: Analyze JJ's sequence

Calculate the ratios (since it's a geometric - like check for non - same - difference). (\frac{9}{3}=3), (\frac{27}{9}=3), but we are looking for a common difference (not ratio as the question is about same amount change). The differences: (9 - 3=6), (27 - 9 = 18). The differences are not the same.
