Nikolai was curious if he could predict how many "likes" an internet video received based on how many views the video had. He took a random sample of videos and noticed a positive linear relationship between number of views and number of likes (both in thousands). Here is computer output from a least-squares regression analysis on his data: Which of these is an appropriate least-squares equation for this model?

idk this answer sorry cant on this one.

step-by-step explanation:

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
