Answer:

the geometric sequence is 36.

Explanation:

To find the 3rd term in a geometric sequence, we can use the following formula:

a_n = a_1 * r^(n - 1)

where:

a_n is the nth term in the sequence

a_1 is the first term in the sequence

r is the common ratio

n is the number of the term we are looking for

In this case, we are looking for the 3rd term, so n = 3. We also know that the first term (a_1) is 25 and the common ratio (r) is 1.2.

Substituting these values into the formula, we get:

a_3 = 25 * 1.2^(3 - 1)

a_3 = 25 * 1.2^2

a_3 = 25 * 1.44

a_3 = 36

Therefore, the 3rd term in the geometric sequence is 36.
