Each term in the sequence below is 9 more than 1/3 the previous term. What is the value of y-x?
81, 36, x, y,...
Plz explain

Answer 1

36/3=12. 12+9=21. X=21. 21/3=7. 7+9=16. Y=16. 21-16=5

Answer 2

Answer:

y - x = - 5

Step-by-step explanation:

Applying the rule gives

x = $\frac{1}{3}$ × 36 + 9 = 12 + 9 = 21

y = $\frac{1}{3}$ × 21 + 9 = 7 + 9 = 16

Thus

y - x = 16 - 21 = - 5
