INSTANT BRAINLIEST Question 5
Write a situation in which positive and negative numbers are used to describe values that have opposite meaning. What does 0 represent in this situation you created?

Acceleration would be one.

If you accelerate at 5m/s/s you gain more speed.

However if you accelerate at -5m/s/s you lose speed.

In this context 0 would be you if you didn't gain speed or lose speed you move at the same speed

Step-by-step explanation:

If you picture a number line 0 would be the starting place. It's like a race. Negative numbers are going backward from the starting point and positive is going forward so 0 would be the starting mark.

, 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

it is x=-4
