Number Patterns and Sequences

Core concept

Other common sequence types include arithmetic sequences (constant difference between terms, like 2,4,6,8...) and geometric sequences (constant ratio between terms, like 2,4,8,16... where each term doubles). Recognising which type of sequence a pattern follows — and correctly identifying its rule — allows prediction of future terms without needing to write out the entire sequence, a valuable skill in both pure mathematics and applied fields like finance (compound interest follows a geometric pattern).
