Suppose a furniture manufacturer ships their products to distributors in pairs (so there are two items sent in each box). The weights of furniture pieces very significantly, but the manufacturer wants to make sure the weight of each package is about the same. From this information the correlation between the weights of the two individual furniture pieces will be .

, 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
