Meaning and Types of Sequence
SEQUENCES:
A sequence is an ordered list of numbers whose subsequent values are formed based on a definite rule. The numbers in the sequence are called terms and these terms are normally separated from each other by commas.
Examples:
2, 4, 6, 8, 10,……
Rule: Addition of 2 for subsequent terms.
70, 66, 62, 58, 54,……
Rule: Subtraction of 4 for subsequent terms.
3, –6, 12, –24,……
Rule: Multiply each term by –2.
There are many types of sequences. We shall be considering the Arithmetic Progression and Geometric progression.
