Tell weather the sentence is arithmetic if it is what is the common diffrance? -12 -7 -2 3

arithmetic sequence with d = 5

Step-by-step explanation:

The sequence is arithmetic if a common difference d exists between consecutive terms

d = - = - = ....

a₂ - a₁ = - 7 - (- 12) = - 7 + 12 = 5

a₃ - a₂ = - 2 - (- 7) = - 2 + 7 = 5

a₄ - a₃ = 3 - (- 2) = 3 + 2 = 5

Since there is a common difference of 5 between consecutive terms of the sequence, it is arithmetic

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
