How do I do this I don’t understand it

Step-by-step explanation:

In order to find slope, first you must find two different points on the line. In this case, they are (0, 0) and (4, 3). Rise is the change in the Y value between the two points. Run is the change in the X value between the two points. (0, 0) goes up 3 and over 4 to become (4, 3). Therefore, the slope of the line is

Keep in mind that when finding slope, you go from left to right, so there are negative slopes, and I assume you'll be getting into those soon!

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
