If 12 > 8.5 > x > y > z, what is the value of z?

(1) The five numbers above constitute an evenly spaced set
(2) y = 1.5


Project DS Butler Data Sufficiency (DS3)

Question type: Value

(1) The five numbers above constitute an evenly spaced set.
We see that this is an evenly spaced set i.e. an AP whose largest term is 12 and CD is 12-8.5 = 3.5.
12, 8.5, x, y, z is in AP.
Z can be found out. No need to calculate z as sufficiency is required.
Sufficient

(2) y = 1.5
Nothing can be known about Z
Insufficient

Answer A
