What is the number you are multiplying by in a sequence

See below.

Step-by-step explanation:

This type of sequence is called geometric and the number you multiply by is called the common ratio.

For example: the sequence 1, 2, 4, 8 - each term is multiplied by the common ratio (2) to get the next term. 1 * 2 = 2, 2 * 2 = 4, 4*2 = 8 and so on,

common ratio

Step-by-step explanation:

When you have a geometric sequence

an = a1 r^ (n-1)

The term r is call the common ratio, which is the number we are multiplying by each time
