Kyrie 20 16 12 8
B.

Jake 4 8 12 16
Kyrie 20 17 14 11
C.

Jake 22 18 14 10
Kyrie 8 11 14 17
D.

Jake 3 6 9 12
Kyrie 18 14 10 6

Answer 1

To determine which table shows Jake's and Kyrie's number patterns, let's analyze their rules:

Jake's rule is to "add 3":
- Starting with a number, each subsequent number is obtained by adding 3.
- For example, if he starts with 1:
- 1 + 3 = 4
- 4 + 3 = 7
- 7 + 3 = 10, etc.

Kyrie's rule is to "subtract 4":
- Starting with a number, each subsequent number is obtained by subtracting 4.
- For example, if he starts with 20:
- 20 - 4 = 16
- 16 - 4 = 12
- 12 - 4 = 8, etc.

Now, let's review each option:

**A.**
- Jake: 1, 5, 9, 13 (this follows his pattern since 1 + 3 = 4, 4 + 3 = 7, but it does not fit here)
- Kyrie: 20, 16, 12, 8 (this is correct for Kyrie's subtracting pattern)

**B.**
- Jake: 4, 8, 12, 16 (this is a valid pattern where 4 + 3 = 7, but it does not fit since it starts at 4)
- Kyrie: 20, 17, 14, 11 (this does not fit his subtracting pattern)

**C.**
- Jake: 22, 18, 14, 10 (this does not fit his adding 3 pattern, as it decreases instead)
- Kyrie: 8, 11, 14, 17 (wouldn't fit subtracting 4)

**D.**
- Jake: 3, 6, 9, 12 (adding 3 works: 3 + 3 = 6, 6 + 3 = 9, 9 + 3 = 12)
- Kyrie: 18, 14, 10, 6 (subtracting 4 works: 18 - 4 = 14, 14 - 4 = 10, 10 - 4 = 6)

Thus, the correct table that shows their number patterns is **D**.
