This document provides an introduction to sequences and series. It begins by giving examples of sequences found in nature, daily life, and other real-world contexts. It then defines what a sequence is mathematically and provides examples of finite and infinite sequences. The document provides exercises for students to practice identifying patterns in sequences and generating additional terms. It also contains lessons on key concepts like the nth term of a sequence and the domain of a sequence function. The goal is for students to demonstrate understanding of sequences, polynomials, and solving related problems in different disciplines.
This slide gives an introduction to the concepts factors and multiples, which go hand in hand in explaining numbers.

Sequences can be observed from how the petals and leaves of plants are
arranged. The growth of plants and human follow a certain stage and
pattern.

SEQUENCE β is a function whose domain is the set of
natural numbers or a subset of consecutive positive integers.
Natural Number are
the set of counting
numbers.
Example 8:
Use the functional Notation F(n) = 2n β 3, where n is a natural number, to write an
infinite sequence.
If n=1
F(1) = 2(1) β 3
= 2 β 3
= -1
If n=2
F(2) = 2(2) β 3
= 4 β 3
= 1
If n=3
F(3) = 2(3) β 3
= 6 β 3
= 3
If n=4
F(4) = 2(4) β 3
= 8 β 3
= 5
The sequence is {-1, 1, 3, 5, β¦ }.
