The Students' Conjectures: Two students, Ernest and Denise, are training for a swim half-
marathon in 10 weeks, and they disagree about their training schedule. If they follow Ernest's
suggested training schedule, will they be ready to swim 5 km in time for the half-marathon?
1. Complete the table to summarize each student's suggested training
schedule. ( 2 points : 1 point for each row of the chart)
Classmate Conjecture
Ernest
1, 1.25, 1.5, 1.75, 2, 2.25…. 10 weeks
Denise
1, 1.5, 2, 2.5, 3, 3.5… 10 weeks

2. Do the distances they swim every week make an arithmetic sequence?
Why? (1 point)
Analyzing the Data:
3. Fill out the schedules for the first four weeks of training.
