(5)/(9,) (5)/(3,) 5,15,45 are these numbers a sequence of geometric numbers

It is a sequence of geometric numbers.

Step-by-step explanation:

A sequence or series of numbers where each term after the first term is found by multiplying it with a fixed or certain number is called a geometric sequence or geometric progression.

We can check whether the given series is geometric or not by dividing each term by its previous term to see if their common ratio is the same.

Since the common ratio is the same, therefore it is a sequence of geometric numbers.

step-by-step explanation:

in which figure is point g a centroid

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
