Discovering algebra is a big part of KS3 Maths. In algebra, we use letters instead of numbers. For example, the letter 'n' (often in italics) shows where a term is in a sequence, and we call it the 'nth' term.
Figuring out the rule for a number pattern can be easy or a bit tricky. Have you heard of the Fibonacci sequence? It creates a cool spiral pattern seen in nature. The rule: add the previous two numbers to find the next one. The nth term? Well, that's for advanced maths - no need to worry about that just yet!
Are Quizzes the Key to Children's Success? Find OutLet's try an easier example. If a sequence starts with 5 and goes up in twos, the nth term is 2n + 3 (like 2 x 1 + 3 = 5, 2 x 2 + 3 = 7). It might seem tricky, but work through this quiz and read the helpful comments – you'll soon catch on to the idea!
