Problem 9:

In | Out
0 | 4
2 | 6
6 | 10
7 | ?

Look at pattern:
0 → 4 (+4)
2 → 6 (+4)
6 → 10 (+4)
So Rule: Add 4

Then 7 → 11 (7 + 4)

✔ Rule: Add 4; Last box: 11

---

Problem 10:

In | Out
2 | ?
6 | 10
14 | 18
15 | 19

Check differences:
6→10 = +4
14→18 = +4
15→19 = +4
So Rule: Add 4

Then 2 → 6 (2 + 4)

✔ Rule: Add 4; First box: 6

---

Problem 11:

In | Out
1 | 2
12 | ?
14 | 15
15 | 16

Check:
1→2 = +1
14→15 = +1
15→16 = +1
Rule: Add 1

Then 12 → 13 (12 + 1)

✔ Rule: Add 1; Missing box: 13

---

Problem 12:

In | Out
4 | 1
9 | 6
11 | 8
17 | ?

Differences:
4→1 = -3
9→6 = -3
11→8 = -3
Rule: Subtract 3

Then 17 → 14 (17 - 3)

✔ Rule: Subtract 3; Last box: 14

---

Problem 13:

In | Out
4 | ?
5 | 10
9 | 14
10 | 15

Check knowns:
5→10 = +5
9→14 = +5
10→15 = +5
Rule: Add 5

Then 4 → 9 (4 + 5)

✔ Rule: Add 5; First box: 9

---

Problem 14:

In | Out
5 | 0
6 | 1
8 | ?
13 | 8

Check:
5→0 = -5
6→1 = -5
13→8 = -5
Rule: Subtract 5

Then 8 → 3 (8 - 5)

✔ Rule: Subtract 5; Missing box: 3
