If x = 1, y = 7, and z = 15, determine a number that when added to x, y, and z yields consecutive terms of a geometric sequence. What are the first three terms in the
geometric sequence?

The first three terms in the geometric sequence are 18, 24, 32.

Step-by-step explanation:

A number when added to that yields consecutive terms of a geometric sequence is an unknown number

Given

We know

Recall that a geometric sequence is in the form

Therefore, once   are consecutive terms,

To find the ratio, for

we know

Therefore,

The ratio is therefore

Therefore, the first three terms in the geometric sequence are 18, 24, 32.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
