Daisy made bread. The equation B = 4f shows the number of loaves of bread baked based on the amount of flour used, where B is the number of loaves of bread made and d is the amount of flour used. Find out the constant of proportionality.

k=4

Step-by-step explanation:

-The constant of proportionality  is defined as the ratio between two directly proportional variables.

-Given that B=4f

#The constant of proportionality is calculated as:

- the equation can be written in the form y=kx,

where y varies directly with x and k is the constant of variation:

Hence, B varies directly with f with a constant of proportionality k=4

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
