You know the Golden Ratio, but what is the Silver Ratio?

In this short math video we will use the common ratio of a geometric sequence to find the first term. We will review the definition of a geometric sequence. A geometric sequence, is a sequence of non-zero numbers where each term after...

A video entitled "Recursive Formula Geometric" that covers the adding numbers to a given sequence.

Pupil outcome: I can appreciate that abstract sequences can have negative values. Key learning points: - When you move away from physical representations of sequences, you can think abstractly. - You can consider what happens if there...

Pupil outcome: I can use my knowledge of non-linear relationships to solve problems. Key learning points: - If you can spot a sequence, it is possible to predict behaviour. - By predicting future behaviour, you can plan how to react. -...

Pupil outcome: I can represent geometric sequences graphically and appreciate the common structure. Key learning points: - A geometric sequence looks like a curve when sketched (common ratio > 1 or < 1). - The gradient increases sharply...

Pupil outcome: I can use my enhanced knowledge of sequences to solve problems. Key learning points: - Compound interest can be thought of as a geometric sequence. - You can apply your knowledge of geometric sequences to solve compound...

Pupil outcome: I can appreciate that not all sequences are linear. Key learning points: - You can identify different types of sequences. - If there is a common difference, the sequence is arithmetic. - If there is a common ratio, the...

Pupil outcome: I can recognise a special number sequence. Key learning points: - You can identify an arithmetic sequence by checking for a common difference between terms. - You can identify a geometric sequence by checking for a common...

Pupil outcome: I can recognise the features of a geometric sequence and continue it. Key learning points: - Identifying a common ratio between each term can help us identify a geometric sequence. - Divide each term by its previous...

Pupil outcome: I can appreciate that there are other number sequences and the limitations of only seeing a few terms of a sequence. Key learning points: - There are more sequences than the ones seen so far. - A numerical sequence is just...

Pupil outcome: I can appreciate the features of a geometric sequence. Key learning points: - Arithmetic sequences are not the only type of sequence. - In a geometric sequence, there is still a first term. - Instead of a common...

In this video, we derive the rule for writing geometric sequences using the "n-1" notation.

In this video we tell the tale of the ancient Indian traveller who beat a king at a game of chess and used his knowledge of exponential growth to become rich!

This video covers how to write an expression to represent a sequence of numbers e.g. 5, 9, 13, 17, 21... could be expressed as 4n + 1 This video is suitable for maths courses around the world. KS3 - All on your course GCSE Foundation -...

A sequence is a set of values that makes a pattern. The differences between the arithmetic sequence, geometric sequence and Fibonacci will be discussed.

This video explains the concept of geometric sequences and their relationship to exponential functions. It covers the explicit rule for geometric sequences, how to find specific terms in the sequence, and how to graph the sequence on a...

👉 Learn how to write the rule of a sequence given a sequence of numbers. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. To write the explicit formula of...

👉 Learn how to find the nth term of a geometric sequence. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. A geometric sequence is a sequence in which...

👉 Learn how to determine if a sequence is arithmetic, geometric, or neither. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. There are many types of...

In this lesson, students will learn about geometric sequences and how they can be written using both recursive and explicit rules. They will understand the difference between the common ratio and the first term in the sequence, and how...

👉 Learn how to find the geometric sum of a series. A series is the sum of the terms of a sequence. A geometric series is the sum of the terms of a geometric sequence. The formula for the sum of n terms of a geometric sequence is given by...

👉 Learn how to find the nth term of a geometric sequence. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. A geometric sequence is a sequence in which...
