The graph shows the price, in dollars, of different numbers of muffins at david's store. the table shows the price, in dollars, of different numbers of brownies at the same store.
a graph shows number of muffins on x-axis and price of muffins on y-axis. the x-axis scale is shown from 0 to 12 at increments of 2, and the y-axis scale is shown from 0 to 80 at increments of 10. a straight line joins the ordered pairs 2, 10 and 4, 20 and 6, 30 and 8, 40 and 10, 50 and 12, 60.

And one brownie is 3$

Then it's easy subtraction (5-3) and you get 2$

, 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

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
