    Sequence
In summary, the sequence follows a 2:1 ratio and each number represents the area of a larger rectangle. The next number in the sequence cannot be determined mathematically, but it can be visualized by doubling the length of the previous rectangle.

2, 2, 8, 72, 392, 2312, ?

The sequence can be represented visually by the attached image.

The smallest rectangles are 2x1. Every rectangle has a 2:1 ratio. Each number in the sequence represents the area of each successively larger rectangle.

I can figure out the next number, but I can't figure out how to represent it mathematically.

Welcome to PF aykantspel.

Suppose that you have somewhere a rectangle with sides of length L and 2L. Possibly looking at the picture, can you say in terms of L what the sides of the next bigger rectangle will be?

You can start by drawing an example: if L = 1 you start with a 2 x 1 rectangle, what will be the size of the next?
 

What is the next number in the sequence?

The next number in a sequence can be determined by identifying a pattern or rule in the sequence and applying it to the existing numbers. However, not all sequences follow a predictable pattern, so it may not be possible to determine the next number.

What is the purpose of finding the next number in a sequence?

Finding the next number in a sequence can help to identify patterns and relationships among numbers, which can be useful in various mathematical and scientific applications. It can also be a fun and challenging puzzle to solve.

What are some common types of sequences?

Some common types of sequences include arithmetic sequences, where the difference between consecutive terms is constant, and geometric sequences, where the ratio between consecutive terms is constant. Other types include Fibonacci sequences, prime number sequences, and triangular number sequences.

What strategies can be used to find the next number in a sequence?

Strategies for finding the next number in a sequence include identifying patterns, using algebraic equations or formulas, and looking for relationships between numbers. Visualizing the sequence using graphs or diagrams can also be helpful.

Are there any tools or resources available for solving sequence problems?

Yes, there are many online resources and mathematical tools available for solving sequence problems. These include online calculators, sequence solvers, and tutorials on identifying patterns and solving different types of sequences. Additionally, textbooks and math websites may offer practice problems and solutions for sequence puzzles.
