1.5, 2.3, 3.1, 3.9,.... Multiply this number by 10 15 23 31 39 ....
Take their difference which is 8
Then 39+8=47
Now divide it by 10 which gives answer 4.7.

2.3-1.5 = 0.8.
3.1-2.3 = 0.8.
3.9-3.1 = 0.8.
4.7-3.9 = 0.8.
3.1-2.3 = 0.8.
3.9-3.1 = 0.8.
4.7-3.9 = 0.8.

1.5 + 0.8 = 2.3,
2.3 + 0.8 = 3.1,
3.1 + 0.8 = 3.9,
3.9 + 0.8 = 4.7.
2.3 + 0.8 = 3.1,
3.1 + 0.8 = 3.9,
3.9 + 0.8 = 4.7.

Assume that there is no (.) in the series,
15 , 23 , 31 , 39
+8 +8 +8
Add 8 in the next numbers,
So, adding +8 in the 39 the answer will be 47.
And finally, the answer is 4.7.

The difference between first and second digit is 0.8.
So, by adding of 0.8 to every digit incressing order 3.9+0.8 = 4.7.
