Answer:

32, 16, 8, 4, 2, 1

Step-by-step explanation:

The geometric mean can be represented by
image.

Which is the mean of the product of n numbers, used to find the average of a geometric progression.

Don't get confused by geometric mean, it is only asking you about the next numbers in the geometric sequence given the first and sixth term.

The explicit rule for a geometric sequence can be modeled by:


image

Where
image is the nth term,
image is the first term in the sequence, n is the term number, and r is the common ratio.

Since we already know the first term,
image will simply be 32.

Since we know it's geometric, there will be an exponential relationship, which means that we will use the geometric mean to find the common ratio.

There are 6 total terms, r is raised to the n – 1 so 6 – 1 = 5, and that will be the degree of this root.


image =


image =


image.

Therefore:
image.

Using all the information we have, we can find the explicit rule:


image


  • image = 32

  • image


image


image

________________________________

We can test that this works by substituting the number location of the term you want to find.

For instance:
