Jul 23, 2025 · The following are the key formulas associated with arithmetic sequences, including ways to find the n-th term, the sum of terms, the common difference, and the number of terms in a sequence.

Sep 1, 2025 · In fact, the arithmetic sequence is the discrete counterpart of the linear function y = mx + b: the slope m corresponds to d, and the intercept b relates to the starting value.

In an arithmetic sequence the difference between one term and the next is a constant. In other words, we add the same value each time ... infinitely. Example: 1, 4, 7, 10, 13, 16, 19, 22, 25, ... This …
