Maura's class is painting the brick wall behind the basketball court. 19 bricks were already painted, and each student paints 20 more bricks in whatever
color he or she wants.
Let s represent the number of students and b represent the total number of
painted bricks.
Use the function b = 20s + 19 to find the value of b when s = 8.

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
