Worked Example 1
Multiplying Rule
Start at 3 and multiply by 3. Write the first four numbers.
- 11st: 3
- 22nd: 3 × 3 = 9
- 33rd: 9 × 3 = 27
- 44th: 27 × 3 = 81
Answer: 3, 9, 27, 81

What Is Benchmark MA.4.AR.3.2?
Students generate a number pattern from a given rule, describe it, and extend it, in math and real-world settings.
For example, the rule "add 14, starting at 5" generates 5, 19, 33, 47. Students also notice features of a pattern, such as whether the numbers are all odd or alternate odd and even.
Official benchmarkGenerate, describe and extend a numerical pattern that follows a given rule.

Worked Examples
Worked Example 2
Describe a Pattern
Start at 100 and subtract 15. Write the first four numbers and describe the pattern.
- 1100 − 15 = 85, 85 − 15 = 70, 70 − 15 = 55
- 2The numbers go down by 15 and alternate between ending in 0 and ending in 5.
Answer: 100, 85, 70, 55
Common Mistakes to Watch For
Using the wrong operation
Wrong:Start at 2 and multiply by 2: 2, 4, 6, 8
That pattern adds 2. Multiplying by 2 gives 2, 4, 8, 16.
Skipping the starting number
Wrong:Start at 5 and add 4. The first four numbers are 9, 13, 17, 21.
The starting number is the first number: 5, 9, 13, 17.
Helpful Math Tip
Look for real patterns, like saving the same amount each week or a plant growing a set amount, and make a table.
