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.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
