Find the ratio (r) between adjacent members
a₂/a₁=96/128=0.75
a₃/a₂=72/96=0.75
a₄/a₃=54/72=0.75
The ration (r) between every two adjacent members of the series is constant and equal to 0.75

The common ratio is 0.75.

Given that,

  • The numbers are 128,96,72,54.

Based on the above information, the calculation is as follows:

[tex]=96\div 128=0.75\\\\=72\div 96=0.75\\\\=54\div 72=0.75[/tex]
