Bob and Alice have designed and created a website for their high school. The first week they had 5 visitors to the site; the second week, they had 10 visitors; and during the third week, they had 20 visitors. If the trend continues, how many visitors can they expect in the fifth week? Explain your answer.

80 visitors

Step-by-step explanation:

From the above question, we can see that:

The trend is explained using geometric sequence

The formula for Geometric sequence is given as:

an = ar ^n - 1

Where a = first term

r = common ratio

n = number of terms

an = nth term

From the above question, let the number of term be equal to the number of weeks.

First week = First term = 5

Second week = Second term = 10

Third week = Third term = 20

Common ratio = a2/a1 = a3/a2 = 10/5 = 20/10 = 2

We are to find the number of visitors for the Fifth week = fifth term,

Hence:

a5 = 5 × 2^5 - 1

a5 = 5 × 2^4

a5 = 80 visitors

The number of visitors we can expect for the fifth week = 80 visitors

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

answer: i guess 5 units?
