What is the common ratio of the geometric sequence 625 125 25 5 1?

Answer 1

It is 0.2

Answer 2

Just divide any number in the sequence by the next number in the sequence. To be on the safe side, you may want to check in more than one place - if you get the same result in each case, then it is, indeed, a geometric sequence.

Answer 3

The common ratio of a geometric sequence is found by dividing any term by the previous term. In this case, to find the common ratio, we can divide each term by the previous term: 625/125 = 5, 125/25 = 5, 25/5 = 5, and 5/1 = 5. Therefore, the common ratio of the geometric sequence 625, 125, 25, 5, 1 is 5.

Answer 4

A geometric sequence is defined by the next term being the common ration times the current term.

To find the common ratio in a geometric sequence divide any number by the previous number:

125 ÷ 625 = 1/5 = 0.2

25 ÷ 125 = 1/5 = 0.2

5 ÷ 25 = 1/5 = 0.2

1 ÷ 5 = 1/5 = 0.2

If this division does not give the same value each time, then the sequence is not a geometric sequence or you've made a mistake).

For the geometric sequence 625, 125, 25, 5, 1 the common ratio is 0.2

Answer 5

625/125
