The mean of your question would be -2.5
The ordered pairs are probably (0,10) and then (-1,5).
Answer:
-40.5, 60.75, -91.125
Step-by-step explanation:
first you want to find the common difference. So just divide 12 by -8, which is -1.5 and then multiply 27 by -1.5, which is -40.5 and continue two more times.
Answer:
12
Step-by-step explanation:
(-15)/(-18) = 10/x cross multiply expressions
-15x = -180 since both sides are negative we can write without the sign
15x = 180 divide both sides by 15
x = 12
