Answer:
In this sequence, the common ratio (r) is 5, as each term is obtained by multiplying the previous term by 5.
Explanation:
In a geometric sequence, the common ratio (r) is found by dividing any term by the previous term. Let's calculate it for the given sequence:
r = 5 / 1 = 25 / 5 = 125 / 25 = 625 / 125
Now, simplify these ratios:
r = 5
r = 5
r = 5
r = 5
In this sequence, the common ratio (r) is 5, as each term is obtained by multiplying the previous term by 5.
