This is a learning material (Module) It contains lesson on finding the common difference and the nth term of a common sequence. It helps develop learners' skill in differentiating finite and infinite sequence, finding the common difference and nth term of an arithmetic sequence, and solving problems involving arithmetic and harmonic sequence.
Objective
1. to recall sequence and differentiate finite and infinite sequence
2. to find the common difference and nth term given the first few terms of an arithmetic sequence
3. to find the first term and common difference or a specified nth term given two terms of an arithmetic sequence
4. to solve problems involving arithmetic means and harmonic sequence.
