Episode 10 — Patterns and Sequences

Arithmetic Sequences

Learners will be able to:

• Identify the common difference in an arithmetic sequence. • Calculate the value of the nth term using the formula TN = A + (N - 1)D. • Determine if a given sequence is arithmetic by checking for a constant difference between successive terms. • Find the general term of an arithmetic sequence when given two terms, using simultaneous equations to solve for A and D. • Generate the first three terms of an arithmetic sequence when given the values of A and D.
