Key Concepts

Common Difference and Slope

Both arithmetic sequences and linear functions involve a constant that signifies the rate of change; for arithmetic sequences, it is known as the common difference, while for linear functions it is the slope. This constant underpins the regular progression found in each, linking the discrete steps of an arithmetic sequence with the constant rate of change in a continuous linear function.

Discrete versus Continuous Domains

A key difference between arithmetic sequences and linear functions lies in their domains and representations. Arithmetic sequences are defined for discrete, typically integer, positions and emphasize step-by-step progression, whereas linear functions are defined over a continuous range of inputs, representing a smooth and uninterrupted relationship between variables.

Arithmetic Sequence

An arithmetic sequence is a list of numbers in which each term after the first is found by adding a constant value, called the common difference, to the previous term. This concept is fundamental in discrete mathematics and algebra, as it encapsulates the idea of a pattern or progression defined by a recurrent addition operation.

Linear Function

A linear function describes a relationship between two variables with a constant rate of change, often expressed in the slope-intercept form (y = mx + b). Linear functions are a core element of algebra and calculus, representing continuous relationships where changes in one variable produce proportional changes in the other.
