The diameters of the circles given are listed as: 2.5 cm, 3.1 cm, 3.7 cm, and 4.3 cm. It can be observed that there is a common difference between the terms of the progression such that the difference between the first two terms is 0.6 cm. The difference between the third and the second is also 0.6, and so on. Thus, the equation that will be able to represent the given is,
<em> f(n) = 2.5 + 0.6(n - 1)</em>

^ This is the tenths place.
The number after it is 4, which is less than 5. So we round down to 0.8.
