Jennifer has started a blog and is using the bar chart below to keep track of how many followers she has, how many followers will she has on day n, pattern is adding 2 followers every day, what would be the rule ?

2n - 1, where "n" is the number of days.

Step-by-step explanation:

By looking at the bar graph.

We list the following information.

Day           The number of followers

1                            1

2                          3

3                          5

4                          7

So, the number of followers increase by 2 each day passes.

This is an arithmetic sequence.

The sequence is 1, 3, 5, 7.....

So the rule

This is the n-term of the arithmetic sequence.

Here and n is the number of days.

Plug in these values in the above sequence, we get

The general rule = 1 + (n -1)2

= 1 + 2n-2

= 2n - 1

So the general rule = 2n - 1

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
