Arithmetic Sequences

This topic covers identification of arithmetic sequences, finding the common difference between the terms, and identifying functions in arithmetic sequences.

Topic: Identify Arithmetic Sequences

  • A sequence is said to be arithmetic if the difference between one term and the next is always the same

  • The difference between any two terms of an arithmetic sequence is called the common difference

  • To identify an arithmetic sequence, find the difference of each term and its next term. If the difference is constant, the sequence is arithmetic

Topic: Identifying Functions in Arithmetic Sequences

  • To find the function, look for a pattern in the sequence

  • Use y to identify the term in the sequence and n to identify the term’s position
