Question

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 1

answer A. next=now •3

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"

Answer 2

A

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
