The pattern in this series is that each number increases by 0.8.

Starting with 1.5, if you add 0.8, you get 2.3.
If you add 0.8 to 2.3, you get 3.1.
If you add 0.8 to 3.1, you get 3.9.

So, to find the next number in the series, you should add 0.8 to 3.9.

3.9 + 0.8 = 4.7

So, the next number in the series should be 4.7.
