An arithmetic sequence is a list of numbers where each number is obtained by adding the same value to the previous number. This value is called the 'common difference.' For example, consider the sequence: 2, 5, 8, 11, 14, ... The common difference here is 3 because we add 3 to each number to get the next one. To find any term in the sequence, you can use this formula: 💡 nth term = first term + (n - 1) * common difference For example, the 4th term (n = 4) would be: 4th term = 2 + (4 - 1) * 3 = 2 + 3 * 3 = 2 + 9 = 11 The sum of the first 'n' terms in the sequence is given by: Sum = (n/2) * [2 * first term + (n - 1) * common difference] Arithmetic sequences are helpful in various areas like calculating averages, predicting future values, and understanding patterns in many everyday situations. They are an essential part of math and can be fun to explore!
