Question

What is the common ratio of the geometric sequence below? 625, 125, 25, 5, 1, ... Brainly?

Answer 1

if every number is divided by 5 the another number comes

Answer 2

Answer:

The common ratio is 1/5

Step-by-step explanation:

The given geometric sequence is 625, 125, 25, 5, 1, ...

The first term of the sequence is 625.

The common ratio of a geometric sequence represented by 'r' is the ratio of two consecutive terms.

Hence, in order to find the common ratio we can take the ratio of second term and the first term.

$r=\frac{125}{625}\\\\r=\frac{1}{5}$

Thus, the common ratio is 1/5
