Identify the Patterns

Understanding Patterns ๐Ÿ”ข

Identifying patterns is a core skill in math that helps you predict what comes next in a sequence of numbers or objects. For the TABE test, patterns usually follow a simple rule. You just need to figure out what that rule is.

There are two main types of patterns you'll see:

1. Patterns of Addition or Subtraction

These patterns are made by adding or subtracting the same number over and over.

Example 1: A pattern of addition

  • Sequence: 2,5,8,11,...

  • The Rule: To get from one number to the next, you add 3. (, , etc.)

  • Next Number: To find the next number, just add 3 to the last number: .


Example 2: A pattern of subtraction

  • Sequence: 20,18,16,14,...

  • The Rule: To get from one number to the next, you subtract 2. (, , etc.)

  • Next Number: To find the next number, just subtract 2 from the last number: .

2. Patterns of Multiplication or Division

These patterns are made by multiplying or dividing by the same number over and over.

Example 1: A pattern of multiplication

  • Sequence: 3,6,12,24,...

  • The Rule: To get from one number to the next, you multiply by 2. (, , etc.)

  • Next Number: To find the next number, just multiply the last number by 2: .


Example 2: A pattern of division

  • Sequence: 80,40,20,10,...

  • The Rule: To get from one number to the next, you divide by 2. (, , etc.)

  • Next Number: To find the next number, just divide the last number by 2: .

Key Strategy

To find the pattern, look at the first two numbers. Ask yourself: "How do I get from the first number to the second?"

  • If the numbers are getting bigger, you are likely adding or multiplying.

  • If the numbers are getting smaller, you are likely subtracting or dividing.

Once you think you have the rule, check to make sure it works for the entire sequence.
