Which of the following represents the sum 3+(-7)? Assume that red tiles represent negative numbers and blue tiles represent positive numbers. three blue tiles plus seven red tiles three red tiles plus seven red tiles three blue tiles plus seven blue tiles three red tiles plus seven blue tiles

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

i think the correct option is the second option.

, 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

i believe a. 12x≥120 is the answer
