Tipton tile has seen an increase in tile sales over the last few weeks. they sold 5,148 square feet of tile to 44 customers last week. if they are expecting between 60 and 70 people to buy tile this week, about how many square feet of tile can they expect to sell?

from 7020 square feet of tile TO  8190 square feet of tile

Step-by-step explanation:

How i got this was i devided 5,148 by 44 and got 117

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
