Number patterns

Number patterns.

Short lesson: Number patterns

In a number pattern, the same rule takes you from each number to the next.

  • Find the rule. Work out the difference between neighbouring numbers. If it is always the same, that is the rule.
  • Check the rule. Make sure the rule works for every pair of numbers, not only the first two.
  • Continue the pattern. Apply the rule to the last number to find the next one.

Worked example

What comes next? 47, 63, 79, 95, ...

Each number is 16 more than the one before: 63 is 47 + 16, and so on. So the next number is 95 + 16 = 111.

Answer: 111
