Consecutive terms of a GP have a common ratio. if 2, x, y, 16 form a GP.

=> 16/y = x/2

=> x = 32/y

y/x = x/2

Substitute x = 32/y

=> y/(32/y) = (32/y)/2

=> 2y = (32/y)^2

=> 2y^3 = 32^2

=> y^3 = 32^2/2

=> y^3 = 2^(10 - 1)

=> y^3 = 2^9

=> y^3 = 8^3

=> y = 8

x = 32/y = 4

**The value of x = 4 and y = 8**
