The question f=9/5c+32 a proportional relationship

This is not a proportional relationship.

Step-by-step explanation:

A proportional relationship is that one that connects two variables by a constant of proportionality.

This type of relationships can be written as:

X = k*Y

where X and Y are the variables, and k is constant of proportionality.

In our relationship, F=9/5c+32, we can see that we have another term, a 32, so this relation can not be a proportional relationship.

, 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
