Number Pattern

NUMBER PATTERN

Pattern= is a set of ordered list of object or number (figures) which continued adding number to the last number each time.

For example: 5, 10, 15, 20, 25, 30, 35, ….. This sequence has a difference of 5 between each number.

Example of the answer,

T3= 14 – 6n

T3= 14 – 6(3)

T3= 14- 18

T3= -4

PROBABILITY

Probability: is how likely an event is.

Experiment: is a situation involving chance or probability that leads to result called outcome.

Outcome/Sample point: is the result of a single trial of an experiment.

(Certain) event/ sample scale: All the possible outcome of an experiment.

P(A) = The number of ways event "A" lan occur.

Total number of possible outcome

Example,

2, 1, 4, 2, 1, 3

= 2 + 1 + 4 + 2 + 1 + 3

= 13/6 = 2.2

(2 - 2.2)² + (1 – 2.2)² + (4 – 2.2)² + (2 – 2.2)² + (1 – 2.2)² + (3 – 2.2)²

= 0.0256 + 1.3456 + 3.3856 + 0.0256 + 1.3456 + 0.7056

= 6.8336 / 6

Inequalities

INEQUALITIES
- Inequalities is a relation between the two expressions are not the same, the common sign that they use are "not equal", "greater than" and "less than".

Inequalities when using number line.

- Greater than

- greater than and equal to

- Less than

- less than and equal to

Example,

Measure of Dispersion

Arithmetic and Geometric

- An Arithmetic progression is a sequence numbers that the difference of any two successive members is a constant.

- Geometric sequence is a sequence of numbers where each term after the number one got by multiplying the previous one or increased by certain value every time
