Question

Here is a sequence: 500, 100, 20, . . . Explain why this sequence could be a geometric sequence.

Answer 1

A geometric sequence is a sequence in which the numbers are multiplied by a fixed number called the common ratio. For example the sequence 2,6,18,54 all have the common ratio of 3! 2*3=6, and 6*3=18, and 18*3=54!!!!!!!
The answer to this problem would be a geometric sequence! Here’s why:, each term has the common ratio of 1/5!!!!!!! 500*1/5=100....and so on
There fore your answer is this sequence could be geometric because it can be multiplied by a fraction in order to get the next term!!!!!!! Hope this helped
