Answer:
average change ≈ .94
equation: read explanation
Step-by-step explanation:
to find the rate of change, im going to first convert every variable into a decimal, to make things simpler
-2/9 is equal to -0.22 repeating, but we are instructed to round to a hundredth so it stays as 0.22
5/8 is equal to 0.625
so, our sequence is simplified to 2.64, -0.22, -0.35, 0.625
now to find the difference between each term by simply subtracting abs val
2.64-0.22=2.42
0.35-0.22=0.13
0.625-0.35=0.275
the mean or average of these 3 numbers is 0.94166666...
rounded to the nearest hundredth, i got .94
putting this in an expression would look like
(2.42+0.13+0.275)/3
or
[(2.64-0.22)+(-0.22-0.35)+(0.625-0.35)]/4
im not sure if this is what youre looking for but this is the best i can do. i dont know what x or y would be or why i would need them but if you send me an image of the problem in full context i might be able to do better
