# What is the next number? 2, 7, 8, 3, 12, 9

Answer: 13

## Understanding Number Sequences

The given sequence alternates between subtracting and adding a number that increases by 1 each time. Starting with 2, subtract 1 to get 1, add 2 to get 3, subtract 3 to get 0, add 4 to get 4, subtract 5 to get -1, and add 6 to get 5. Continuing this pattern, the next number after 2, 7, 8, 3, 12, 9 is 13 (9 subtract 6 to get 3, add 10 to get 13). Recognizing patterns in number sequences is an important aspect of mathematical problem-solving. It enhances logical thinking and is used in various academic and professional fields, such as computer science, cryptography, and engineering, where pattern recognition is crucial.
