Answer:
Use your calculator to find the line of best fit for the data. ... Age Range, \begin {align*}x\end{align*}, 1-3, 4-6, 7-10, 11-14, 15- ... Here is a sample table for the scatterplot
a_15 = 90
a_n = 6n
Step-by-step explanation:
Given sequence is:
6, 12, 18, 24,...
First of all we have to find the common difference. The common difference is the difference between consecutive terms of an arithmetic sequence.
Here,

The general form for arithmetic sequence is:

Putting the values for a_1 and d

<u>a) Find a15</u>

<u>b) Write an equation for the nth term.</u>
The equation is: a_n=6n
