The thee geometric means are a₂, a₃, and a₄.

1) Find a₃:
    a₃ =  \sqrt{(16)(625)}
    a₃ =  \sqrt{10,000}
    a₃ = 100

2)  Find a₂:
     a₂ =  \sqrt{(16)(100)}
     a₂ =  \sqrt{1,600}
     a₂ = 40

3)  Find a₄:
     a₄ =  \sqrt{(100)(625)}
     a₄ =  \sqrt{62,500}
     a₄ = 250

The three geometric means are:  40, 100, 250

The geometric sequence is: 16, 40, 100, 250, 625
