2. Geometric Sequence – is a sequence of numbers in which each term
is formed by multiplying the previous terms by a number called the common
ratio.
Example1.1.2
a. 3, 6, 12, 24, 48
b. 3, 9, 27, 81, 243

each number in a term is the sum of the two preceding numbers.
Fibonacci Sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, …
Logic Patterns
Pattern recognition is one of the most important skill in solving problems
not only in Mathematics but also in everyday life. Just like in number patterns,
logic patterns also reveal a relationship among the pictures or images. The
ability in logical reasoning and the skill to observe patterns are considered to
be the very essence of Mathematics. In fact, it is one of the most important
and considered as the core component in measuring one’s Intelligence
Quotient (IQ). Items in logical reasoning are commonly included in
standardized tests that are usually administered in career placement
examinations.
