Math worksheet for middle-grade students with 10 problems covering sequences, arithmetic, a pie chart analysis, and algebra.

Explanation:
Let’s go through each question one by one and solve them carefully.

1. 1, 5, 9, 13, ___, ___, ___
Look at the pattern:
5 − 1 = 4
9 − 5 = 4
13 − 9 = 4
So it’s adding 4 each time.
Next: 13 + 4 = 17
Then: 17 + 4 = 21
Then: 21 + 4 = 25

2. 10 − 4 · 2 =
Remember order of operations: multiplication before subtraction.
4 · 2 = 8
Then 10 − 8 = 2

3. 18 / 3 =
18 ÷ 3 = 6

4. 84 ÷ 1 =
Any number divided by 1 is itself. So 84 ÷ 1 = 84

5. Does Ellen spend more time on homework or sports?
Look at the pie chart:
- “homework” slice looks smaller than “sports” slice.
Visually, “sports” is larger than “homework”.
So answer: sports

6. 4 · 3 + 5 · 1 =
Do multiplications first:
4 · 3 = 12
5 · 1 = 5
Then add: 12 + 5 = 17

Now for questions 7–10, use:
a = 2, b = 3, c = 6

7. a + b =
2 + 3 = 5

8. ac =
a × c = 2 × 6 = 12

9. c / a =
6 ÷ 2 = 3

10. 2b =
2 × b = 2 × 3 = 6

Let me double-check all answers:
1. 17, 21, 25 ✔
2. 2 ✔
3. 6 ✔
4. 84 ✔
5. sports ✔
6. 17 ✔
7. 5 ✔
8. 12 ✔
9. 3 ✔
10. 6 ✔

All correct.

Final Answer:
1. 17, 21, 25
2. 2
3. 6
4. 84
5. sports
6. 17
7. 5
8. 12
9. 3
10. 6
