common ratio = a4/a3 = a3/a2

8/a3 = a3/18

(a3)^2 = 8 * 18

(a3)^2 = 144

a3 = 12 or a3 = -12

common ratio = 8/12 or common ratio = 8/(-12)

common ratio = 2/3 or common ratio = -2/3

Answer: 12 or -12

Max was on vacation twice as long as Jared and half as longas Wesley. The boys were on vacation a total of 3 weeks. How many day
lord [1]
Make an equation.
Also, convert 3 weeks into days ⇒ 3 · 7 = 21 days.

x + 2x + 4x = 21

x is Jared.
2x is Max (because half of 4 is 2).
4x is Wesley.

Now solve the equation.

7x = 21
x = 3

Jared = x
Max = 2x
Wesley = 4x

Jared = 3 days
Max = 2(3) = 6 days
Wesley = 4(3) = 12 days
