What is the next term of the geometric sequence?
7, 21, 63

First find the common ratio of this geometric sequence.

We will use .

The second term is 21 and the first term is 7.

So we have and this reduces to or 3.

So, we take the last term in our geometric sequence

and multiply it by the common ratio we just found.

So we have 63 · 3 which is 189.

So the next term in this geometric sequence is 189.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
