Fascinating Fact:

Negative sequences go down instead of up, like 10, 7, 4, 1, they subtract the same number each step, proof that not all progress moves forward.

In 11 Plus Maths, number sequences show how numbers follow set rules. By learning to spot increasing and decreasing patterns, pupils develop logic and prepare for algebraic reasoning.

Key Terms

Arithmetic Sequence: A pattern that adds or subtracts the same number each time.
Decreasing Sequence: A series of numbers that get smaller step by step.
Term: Each individual number or item that forms part of a sequence.

Frequently Asked Questions (Click to see answers)

What is a decreasing number sequence?

A decreasing number sequence is one where each term is smaller than the one before, often by subtracting the same amount each time.

How can I find the pattern in a sequence?

Look at how the numbers change. If the difference between each term is the same, it follows an arithmetic rule.

Are negative numbers used in sequences?

Yes. Negative numbers can appear when a sequence continues below zero, showing values that decrease past the positive range.
