Patterns and Sequences

A sequence follows a rule. In 2, 4, 6, 8โ€ฆ the rule is add 2. Spotting the rule lets you predict the next numbers.

๐Ÿ’ก Fun fact

The Fibonacci sequence adds the two previous numbers: 1, 1, 2, 3, 5, 8โ€ฆ

All about Patterns and Sequences

A sequence is an ordered list of numbers that follows a rule. In 2, 4, 6, 8, the rule is add 2. Finding the rule lets you predict the next numbers in the sequence, even far along the list.

Some sequences multiply, such as 1, 2, 4, 8, where each number is double the one before. Others mix operations or alternate. Looking closely at the differences between terms is the best way to spot the rule.

Frequently asked questions about Patterns and Sequences

What is the rule for the sequence 3, 6, 12, 24?

Multiply each number by 2.

What is a Fibonacci sequence?

A sequence where each number is the sum of the two before it, starting 1, 1, 2, 3, 5, 8 and so on.

How do I find the next term in a pattern?

Work out the difference between terms, or what you multiply by, and apply that same step to the last number.
