Just some fact checking before i turn it in.

one of your classmates was absent on the day that you learned how to write and solve an equation from a contextual situation. your teacher has asked you to explain the four steps and their application to the problem that follows.

natasha stole three fewer bases than twice the number elena stole. if natasha stole 15 bases, how many did elena steal?

using the four steps from this lesson, write and solve an equation to find the number of bases elena stole.

here's what i wrote:

15 + 3 = 18
18 / 2 = 9
elena stole 9.

, 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

, and for

17.08

correct me if i am wrong.
