Math 1002 Practice Problems

1. Use inductive reasoning to predict the next three numbers in the pattern (or sequence).
4, −20, 100, −500, . . .
Step 1: Form a Hypothesis:

Step 2: Make observations related to the hypothesis:

Step 3: Come to a conclusion:

2. Flying West New York City is on eastern standard time, St. Louis is on central standard time (1 hr earlier than eastern standard time), and Las Vegas is on Pacific standard time (3 hr earlier than eastern standard time). A flight leaves New York City at 9 a.m. eastern standard time, stops for 50 min in St. Louis, and arrives in Las Vegas at 1:35 p.m. Pacific time. How long is the plane actually flying?
My answer is 3 hours, 45 minutes.
Leaving 9 am EST, arriving 4.35 pm EST. = 7 hours, 35 minutes less 50 minutes. The actual flying time is 3 hours, 45 minutes.
Is this correct? Is there another way to explain this problem?
