which equation represents the geometric sequence? 3, 9, 27, 81,... A. next=now •3 B. now=next •3 C. next=now • (1/3) D. now=next •9

answer A. next=now •3

Step-by-step explanation:

Looking at the sequence 3, 9, 27, 81, you "see" a that each next number is formed by multiplying the current

number by 3. This is exactly what is stated in answer A. next=now •3

EXTRA:

Mathematically, the function llooks ike f(x) = 3"

A

Step-by-step explanation:

3,9,27,81

This  is geometric sequence.

Common ratio = 2nd term / 1st term = 27/9 = 3

So, the next term is obtained by multiplying the current number by 3

Next = now * 3

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
