Sequences

Question 1

What are the different types of sequences?

Answer 1

A number sequence is a set of numbers that follow a particular pattern or rule to get from term to term. There are four main types of different sequences you need to know, they are arithmetic sequences, geometric sequences, quadratic sequences and special sequences.

Question 2

Linear Sequences

Answer 2

This is a sequence that changes by adding or subtracting the same amount throughout the sequence e.g. 2, 4, 6, 8, 10 or… …200, 195, 190, 185, 180, 175.

Question 3

What is the nth term?

Answer 3

The nth term is a formula that enables us to find any term in a sequence. The ‘n’ stands for the term number. We can make a sequence using the nth term by substituting different values for the term number(n).

Question 4

What is an oscillating sequence?

Answer 4

In mathematics, the oscillation of a function or a sequence is a number that quantifies how much that sequence or function varies between its extreme values as it approaches infinity or a point.

In mathematics, the oscillation of a function or a sequence is a number that quantifies how much that sequence or function varies between its extreme values as it approaches infinity or a point.

Question 5

Fibinachi

Answer 5

The previous two numbers added up to make the next number.

Question 6

Geometric

Answer 6

Multiplying/keeps going by multiple e.g. 3, 9, 27.
