Math worksheet for practicing time patterns with three fill-in-the-blank sequences.

Let’s solve each time pattern step by step.

---

Part a: 1:45, 2:45, 3:45, 4:45, ___

Look at the times:
- From 1:45 to 2:45 → that’s +1 hour
- From 2:45 to 3:45 → also +1 hour
- From 3:45 to 4:45 → again +1 hour

So the pattern is: add 1 hour each time

Next after 4:45 → 4:45 + 1 hour = 5:45

✔ Answer for part a: 5:45

Part b: 8:00, 8:30, ___, 9:30, ___

Look at the known times:
- 8:00 to 8:30 → that’s +30 minutes
- Then we have a blank, then 9:30

If we add 30 minutes to 8:30 → 8:30 + 30 min = 9:00

Then from 9:00 to 9:30 → that’s another +30 minutes ✔

Now, what comes after 9:30? Add 30 more minutes → 9:30 + 30 min = 10:00

✔ Answers for part b: 9:00 and 10:00

Part c: ___, 7:45, 9:15, 10:45, 12:15

We need to find the first missing time. Let’s look at the differences between the given times:

From 7:45 to 9:15:
- 7:45 to 8:45 = 1 hour
- 8:45 to 9:15 = 30 minutes
→ Total = 1 hour 30 minutes

From 9:15 to 10:45:
- 9:15 to 10:15 = 1 hour
- 10:15 to 10:45 = 30 minutes
→ Again, 1 hour 30 minutes

From 10:45 to 12:15:
- 10:45 to 11:45 = 1 hour
- 11:45 to 12:15 = 30 minutes
→ Still 1 hour 30 minutes

So the pattern is: add 1 hour 30 minutes each time

To find the time *before* 7:45, we subtract 1 hour 30 minutes from 7:45.

7:45 minus 1 hour = 6:45
6:45 minus 30 minutes = 6:15

Check: 6:15 + 1h30m = 7:45 ✔

✔ Answer for part c: 6:15

Final Answer:
a. 5:45
b. 9:00, 10:00
c. 6:15
