Fascinating Fact:

The powers of three create a sequence of one, three, nine, twenty seven, eighty one, showing how quickly multiplication builds power.

In 11 Plus Maths, challenging number sequences teach pupils how patterns can grow at increasing rates. Learning about powers and exponents builds a strong foundation for future algebra and problem-solving.

Key Terms

Power: A number multiplied by itself one or more times, such as three squared (3²) equals nine.
Exponent: The small raised number that shows how many times to multiply the base number by itself.
Geometric Progression: A sequence where each term is found by multiplying the previous term by a fixed number.

For further guidance, see our guide on what subjects are tested in the 11 Plus.

Frequently Asked Questions (Click to see answers)

What are powers and exponents in maths?

Powers and exponents show repeated multiplication of a number, such as 2³ meaning 2 × 2 × 2, which equals 8.

What is a geometric progression?

A geometric progression is a pattern where each term is multiplied by a constant, such as 2, 4, 8, 16, 32.

How do I recognise a difficult number sequence?

Difficult sequences often involve powers, alternating signs, or multiple rules, requiring careful pattern recognition and logical thinking.
