# Worksheet: One-Step Input–Output Patterns

In this worksheet, we will practice finding the missing number and identifying patterns in input–output tables using one-step rules.

**Q2: **

Write the first three terms of the pattern described.

- The starting number is
**216**. - The rule is
**divide by 3**.

- A216, 72, 24
- B216, 213, 210
- C216, 72, 12
- D216, 36, 12
- E216, 36, 6

**Q3: **

Find the missing number in this input-output table.

In | 31 | 39 | 56 | 72 | |
---|---|---|---|---|---|

Out | 10 | 18 | 27 | 35 | 51 |

- A 47
- B 35
- C 48
- D45
- E 55

**Q4: **

Isabella is making patterns of rectangles by using the rule add 2 cm to the length.

What is the length of Rectangle 4?

The lengths make the pattern . She notices that the areas of the rectangles also make a pattern. Which of these is the pattern of the areas of the rectangles?

- A
- B
- C
- D
- E

What is the rule for the pattern of the areas?

- Amultiply by 2
- Bmultiply by 4
- Cadd 8
- Dadd 2
- Eadd 4
