Layla is using the model to solve a division problem. An area model has 4 shaded parts and 2 unshaded parts. The shaded part is labeled two-thirds.
Which question would the model be most helpful in solving?
How many One-sixths are in 4?
How many One-sixths are in Two-thirds?
How many Two-thirds are in 4?
How many Two-thirds are in One-sixth?

, 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
