This is referred to as a geometric progression - as opposed to an arithmetic progression, where each new number is achieved via addition or subtraction.

What is next number in sequence 5 10 20 40?

The next number in the sequence 5, 10, 20, 40 is 80. Each number in the sequence is multiplied by 2 to get the next number. So, 40 multiplied by 2 equals 80.


What comes next -5 25 -125 625?

Each value is being multiplied by -5. The next value will be -3125.


What comes after Tredecuple?

After "tredecuple," which refers to a quantity multiplied by 13, the next term in the sequence of multipliers is "quattuordecuple," which represents a quantity multiplied by 14. This naming convention follows the Latin roots for numbers, where each prefix corresponds to the numerical value in order.


What is the difference between an arithmetic sequence and a geometric sequence?

In an arithmetic sequence the same number (positive or negative) is added to each term to get to the next term.In a geometric sequence the same number (positive or negative) is multiplied into each term to get to the next term.A geometric sequence uses multiplicative and divisive formulas while an arithmetic uses additive and subtractive formulas.


What is the next number in the sequence 125 -25 5 -1....?

This is a geometric sequence. Each number is multiplied by the same constant, to get the next number. If you divide any number by the previous one, you can find out what this constant is.


what is the pattern in 5,10,20,40.... is it multiply by 2?

Yes, each number is multiplied by 2 therefore the next 2 numbers in the sequence would be 80 & 160


What is the next in line Fibonacci-like sequence 5 5 10 15?

25 It is the Fibonacci sequence multiplied by 5.


What is the sequence of 7 21 63 189 and 567?

The sequence 7, 21, 63, 189, and 567 can be described as each term being multiplied by 3 to get the next term. Specifically, 21 is 7 multiplied by 3, 63 is 21 multiplied by 3, 189 is 63 multiplied by 3, and 567 is 189 multiplied by 3. Thus, the formula for the nth term can be expressed as ( a_n = 7 \times 3^{(n-1)} ).


What comes next 44 22 88 44 176 88?

Well, honey, it looks like we're doubling the number each time. So, following that pattern, the next number should be 352. But who knows, life is full of surprises, just like my love life in the '80s.


What is the missing sequence 27 22.5 18 13.5?

It is reducing by 4.5 each time, so the next value would be 9.


What does the common ratio mean?

The common ratio refers to the constant factor by which each term of a geometric sequence is multiplied to obtain the subsequent term. It is denoted by "r" and can be found by dividing any term in the sequence by the preceding term. For example, in the sequence 2, 6, 18, the common ratio is 3, as each term is multiplied by 3 to get the next. This ratio plays a crucial role in determining the behavior and properties of geometric sequences and series.


What is a non example of arithmetic sequence?

A non-example of an arithmetic sequence is the series of numbers 2, 4, 8, 16, which is a geometric sequence. In this sequence, each term is multiplied by 2 to get to the next term, rather than adding a fixed number. Therefore, it does not have a constant difference between consecutive terms, which is a defining characteristic of an arithmetic sequence.
